Video Transcript for Hopkins LED Breakaway Switch Review

Hey everybody, Ryan here at etrailer. Today we're gonna be checking out and showing you how to hook up the Hopkins LED breakaway switch. Having a functioning breakaway switch is a critical component for your trailer's breaking system. Not only, you know, legally speaking, but for your safety too. So the whole point of a breakaway switch is if you we're in an unlikely disconnect, what would happen is you'd hook one end of your cable up to your vehicle that you're using to tow, and if the trailer came separated, a pin would pull out, and allow power to go through the breakaway switch to your trailer's brakes, applying the brakes, slowing everything down and getting it back under control. So it's really important that this is working, because during that stressful situation, you want to be able to rely on your trailer to do its job.

And this is a good example today of, kind of a breakaway switch that's seen better days. You know, the wires are exposed here where they're going into the switch. the tether's all chewed up, and it seems to be either not working at all, or very intermittently. So the way a breakaway switch works, I have a test light here, you'll always have power on one side of it, all right So I'm getting power there, and you shouldn't have power on the other side until the switch is pulled. So let's say if the switch is pulled, we don't have power there.

So literally if in that, you know, with this not functioning correctly, when this is pulled, then you need the brakes more than ever to slow you down. The breakaway switch isn't gonna let that power go through being that it's defective. So you know, having a simple replacement like this is definitely a great solution to get you back legal and safe again. So I went ahead and got this hooked up, which we will show you how to do in just a minute. I just wanted to have it, kind of, set up so we could see what's going on.

So one of the things that really separates this one from some of the others, there's a couple things, really. Main one being that it has that LED built into it, which is really cool. So when you go to test this, you know, before you tow your trailer, whatever, if you pull that out, and everything's going the way it should, you'll have that red light illuminate saying that it's in- it's, everything's engaged. So pretty cool there. Just a real quick way to make sure you're getting power, and this is working properly, and everything else.

I'm also a fan of the size of it too, so compared to a lot of the other ones, it's pretty small, and because of that, you know, it won't take up a lot of space on your trailer, and allow you to mount this in a lot of different positions or configurations. It's breakaway switch's gonna work with just about every trailer that has brakes out there. You know, the breakaway systems are all pretty much hooked up and wired exactly the same. So great replacement or even a slight upgrade because of that LED, and it is gonna come with a cable too. This is 48 inches, so pretty standard, you know, it's long enough if you need to mount your switch a little further back or whatever, you're probably gonna have the cable length that you need to be able to hook it up to the hitch on your truck. A lot of times when people get to replacing something like this, they're kind of just going over through the whole trailer, and, kind of, freshening everything up. And that's exactly what we did here today. We got a new seven-way plug, new junction box, you know, putting the new breakaway on, even a new replacement battery for our breakaway box, brakes, all that type of stuff. So if that's what you're doing, we carry all this stuff here at etrailer, and can hopefully make things a little bit easier on ya. But other than that, at the end of the day, pretty simple component, yet a critical one, you know, one that you want to work, and one that you need to be able to rely on. So I really like this one with that LED light, kinda adds a little bit to it there. Makes it easy to check. And because of the size, you know, you can mount this thing up just about anywhere you'd like. As far as the installation goes, pretty easy. You mount it up and you got a few wires to hook up. So if you'd like to hang around, we'll go ahead and get started on it now. To begin your install, first thing that I like to do is, kind of, prep the wires coming off. So we'll have a white wire, which will be ground. So I crimped on a ring terminal to it. The black wire, that's gonna be our battery power. So I crimped on a butt connector to it, and the blue wire is gonna go, if the pin we're to be pulled, you know, that's gonna send power back to our brakes. So we'll do this one, and butt connectors and ring terminals are all gonna get hooked up the same way. You can get all that stuff here at etrailer if you need it. You strip the wire back, give it a good twist and then place the butt connector over the end of it, and crimp it down. So now with that, kind of, prepped, we can look at our old breakaway switch, all right, which is right here. And I have a test light, and what we're looking for is for the wire that has constant power. So we check 'em, this is the one that's gonna have constant power. So we'll do this one at a time, because the constant power one, we're gonna want to hook that up to the black wire on our new breakaway switch. So I'm gonna cut this back, I cut a little bit off there. Looks like the wire was a little chewed up but so, actual wire looks good. We'll give that a twist, we'll hook that up to the black wire on our breakaway switch. I'm gonna get that in there, and crimp down. And since I'm using heat shrink style butt connectors, come back with my heat source, and seal up the ends. (heat gun whirs) The other existing wire to our old breakaway switch. Cut that off, strip it back, and this will get hooked up the same exact way that we just did the other one. (heat gun whirs) As far as the ground goes, that'll just have to go to the chassis, you know, the trailer frame. So to prevent from having to drill another hole where I'm gonna actually secure our breakaway switch, I'm just gonna utilize that. That'll work just fine. Just line it up, get our self tapper, and secure this all down. (drill revs) With it all hooked up, it is a good idea to to test everything out. So the sweet thing about this one is, very easy to do that, since it has that light built into it. So pins in, we're all good. If you pull it, we should see that LED illuminate, and we should get power. Which we do, so, 'cause of that being pulled, the power's going through, and we're in good shape. And that'll finish up our look at, and our installation of the Hopkins LED breakaway switch.

Switch mounded up ok. I fabricated a shield to cover the switch so that it would not be jerked around and possibly fail due to wiggling around.

Thank Randy F. for another great review and rating!! Hopkins appreciates your business.

Works great, only used to test but is excellent device with my fabricated bracket to prevent movement


Searched retail stores for this break away switch with LED test light and no luck. E trailer had the exact part delivered to my home in several days and was exactly what I expected.


Replaced a worn out breakaway switch on my '03 Coleman Yuma. Works great.


Order delivery was upgraded, at no cost to me, and delivered in just over 24 hrs. Etrailer was in contact by email from order confirmation to shipping time. I would recommend them to everyone.


This switch was a great replacement for my broken one. Nice way to upgrade as well.


Exact OEM switch replacement for most of our trailers.


I've dealt with Emily several times and she was always
spot on and she is the best !!!
Everything else about Etrailer is terrific !!!
Thank You !!!!


Looks like a good replacement. everything was shipped fast


Not quite like the picture description, but close. There was not a separate activation pin with a ring, only the pin attached to the cable.

  • Do You Have a Replacement Pin and Lanyard for a Trailer Breakaway Switch
    If you have the Tekonsha trailer breakaway kit you will need the Replacement Tekonsha Trailer breakaway Switch, part number 420000, to replace your lost or broken cable and pin. If you have a Hopkins Breakaway system then you can order the Replacement Cable and Pin for Hopkins Breakaway Switches, part number HM20051 which works on the HM20059 and HM20060 breakaway switches.

  • How to Wire Hopkins Breakaway Switch # HM20059 with Hydrastar Electric Over Hydraulic Brake Actuator
    The yellow wire from the Hydrastar # HBA16 will connect to the blue wire of the Breakaway Switch # HM20059. The blue wire from the Breakaway Box # HM20121 connects to the black wire from the switch. The white wire from the switch is strictly a ground for the LED light and should connect directly to the trailer's frame.

  • Re Inserting Pin into Breakaway Switch
    The piece of the switch that pulled out is keyed, so that it can only be inserted back into the switch one way. Try rotating the piece, eventually you will find the position in which it will go in. You will also want to make sure that the pin was not damaged.

  • What are the Functions of the 3 Wires on Hopkins LED Breakaway Switch, # HM20059
    You are correct, the Hopkins LED Breakaway Switch, # HM20059, does have 3 wires. The white wire is the ground wire and should be attached to the trailer frame. The blue wire on the switch will connect to the electric brake wire coming from the trailer side connector. The black wire goes to the break away battery. This part is just a switch, if you need a new system, I recommend Engager Trailer BreakAway Kit with Charger and Tester, # 20099. I have included a link to the installation details...

  • No Brakes On Trailer When Pin Is Pulled On Breakaway Switch
    I have attached a couple of helpful articles that explain how to install and test breakaway systems. I spoke with my contact at Hopkins and they told me that the light should not illuminate unless the cable has been pulled. Since you said the light is blinking when hooked up, it sounds like there may be a problem in the wiring. You can also test the battery to make certain it has a full charge. If you do not have the breakaway system wired correctly, the brakes may not be getting the signal...

  • Can a 3-Wire Breakaway Switch Be Substituted for a 2-Wire Breakaway Switch
    Yes, you can use a 3-wire breakaway switch like part # HM20059 in place of a 2-wire breakaway switch like part # HM20010. The connections will be the same and the only differences is that the 2-wire switch grounds through the mounting hardware whereas the 3-wire switch grounds with a single wire. The blue wire on the switch will connect to the electric brake wire coming from the trailer side connector. The black wire goes to the breakaway battery. If it turns out it is not the switch...

  • Trouble Re-Installing Breakaway Pin Back In Switch
    The majority of breakaway pins are keyed which means they can only be inserted back into the switch one way like the Hopkins LED Breakaway Switch part # HM20059 for example. Therefore, most likely you just don't have the pin in the correct position. That said, if the pin is damaged or there is foreign objects inside the switch that could cause issues as well. Please note, it does take a fair amount of force to remove and reinstall the pin back inside the switch. That said, there isn't...

  • Wiring 3-Wire Breakaway Switch as Replacement for 2-Wire Switch
    You can absolutely wire up a 3-wire breakaway switch like the Hopkins LED Breakaway Switch with 7" Lead Wires # HM20059 to replace your 2-wire switch; the difference is that the 3-wire switch has a dedicated ground wire while the 2-wire switch grounds through its mounting hardware. The Hopkins LED Breakaway Switch # HM20059 has the white ground wire, a blue wire which will splice into the brake wire coming out of your trailer connector and a black wire which will connect to the breakaway box.

  • Where Does 3rd Wire On 3-Wire Breakaway Switch Get Connected To?
    The 3rd wire on a 3-wire breakaway switch like the Hopkins LED Breakaway Switch with 7" Lead Wires # HM20059 gets grounded to the trailer frame or tied in to the main ground on your trailers tongue. The only difference between a 2-wire and 3-wire switch is the 3-wire switch has its own ground wire. I included a wiring diagram of the # HM20059 for you to take a look at.

  • Should Trailer Breakaway Switch to Very Difficult to Pull
    Glad everything worked out okay but sorry to hear about your breakaway pin not doing the ONE JOB it was designed for. I would go with an all new switch just to be careful and because they are relatively inexpensive. I would go with the Hopkins part # HM20059 which we know works well and wouldn't have same issue you had. Just make sure the pin would pull straight from the switch if the trailer was to become disconnected again and you'd be fine. The force to pull the pin shouldn't be too...

  • Replacement Breakaway Kit Switch Recommendation for RV Breakaway System
    Put the pin back in and check the wiring of the switch to make sure nothing was damaged. Nothing should be reset but the switch could have been damaged or the wiring as well. For a replacement switch though we have the Hopkins kit part # HM20059 which would work well as a replacement.

  • LED Status on Hopkins LED Breakaway Switch
    For your Hopkins LED Breakaway Switch part # HM20059 the led indicator should only be lit when the breakaway pin is pulled, and should be solid. When the pin is inserted and the trailer hooked up it should not be on at all. If you do not have the breakaway system wired correctly, the brakes may not be getting the signal from the breakaway box. It sounds like there may be a wiring issue with the breakaway switch. I recommend that you check all your connections, specifically check the white/ground...

  • Recommended Breakaway Switch Kit For Trailer and How Does It Get Wired?
    For a breakaway switch I recommend going with the Hopkins Engager Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger - Top Load # 20400 as it includes the battery with a built in battery charger and tester needed. To wire the # 20400 you will make the following connections: Black wire from the battery to the 12v power wire from your 7-way connector White wire from the battery to the ground wire on your 7-way connector Blue wire from breakaway switch to brake output wire...

  • Replacement Breakaway Pin for Landa ECOS Trailer
    If you can provide me with the brand and model of the breakaway system that is used on your Landa ECOS Trailer then I can go about seeing if we have a replacement breakaway pin for you. However, the breakaway pins are not all universal. Unfortunately, I don't have any information as to what the brand and model is for your trailer. Therefore, the only option we can currently offer you is a new switch and pin for the Trailer Breakaway Kit part # 3802348 for two wire systems or the Hopkins...

  • Can Trailer Breakaway Pin be Easily Substituted If Broken On Trip
    Breakaway plungers are pretty unique so you won't be able to easily substitute something to get you back on the road. I could tell you to cut the wire on the switch so that the brakes would release so that you could get home to order a new switch like with the part # HM20059, but since that's not safe I really can't recommend that as an ideal solution...

  • How To Wire Hopkins LED Breakaway Switch Part HM20059
    In regards to the Hopkins LED Breakaway Switch part # HM20059; the white wire is ground, the black wire is for 12 volt power, and the blue wire is for electric brake output. If you have a two wire switch, the above will work but the Hopkins Replacement Break-Away Switch part # HM20010 would be better since there are less connections but you can use either. The Replacement Break-Away Switch grounds though the mounting hardware which is why an additional ground is not needed.

  • How to Turn Off LED Indicator on Hopkins LED Breakaway Switch
    In order to turn off/deactivate the LED indicator light on the Hopkins LED Breakaway Switch # HM20059 referenced in your question, you simply will not connect the white ground wire on the unit. If the white wire is not grounded, the LED indicator will not function but everything else will work like normal. For a non-LED version, you can also use the Hopkins Replacement Break-Away Switch # HM20010.
