Video Transcript for Hopkins Trailer Breakaway Kit HM20010 Review

Today we're going to be taking a look at the Hopkins replacement break away switch. Now a break away switch is designed to apply power to the trailer brakes to stop a trailer should it become disconnected from its own vehicle. If the trailer and vehicle disconnect, the vehicle actually pulls on the cable, which would pull the pin out of the switch. Once this happens, the trailer brakes are applied, which will bring the trailer to an eventual stop. The kits going to come with the switch. You're going to get your wire leads, you're going to get the pin, and you're going to get a cable. The wire leads are going to measure about 7 inches long.

One wire gets connected to the break away battery. The other wire gets connected to the electric trailer brake wire. The cable right here is a high-strength steel cable. That is going to be covered with a protective coating, which is going to keep it from fraying, and it's going to keep it from scratching anything that it comes into contact with. The length of our cable is 4 feet long. Again, it's got the pin that connects into the box.

The other end of the cable would connect to the tow vehicle. The switch right here, I just want to go over a few basic measurements. Overall length, including the bracket at the back, that's going to give us a measurement of about 3 inches. Just measuring the box, that's going to give us a length measurement of about 2 inches. Width measurement I going to be about an inch and a half.

Thickness is going to be about 1 inch. Diameter of that mount hole, that's going to measure about a quarter of an inch, and mounting hardware is not included. That's going to do it for today's look at the Hopkins replacement break away switch.

I accidentally let my Breakaway unit go with a Jeep I sold. Therefore I needed a new one for my new Jeep which I tow behind my motorhome. Brake Buddy wanted close to $80 for a replacement Breakaway unit and this one cost me less than $10 and a little bit of wiring. Works great. 559067

Do you have a question about this Accessories and Part?


  • Easy Solution for Lost Pin for Trailer Breakaway System
  • The TAP Engager brakeaway kit you have on your trailer is a standard style of breakaway very similar to the Hopkins Engager part # 20099. For a replacement pin setup that would work well we have the # HM20010 which gives you a new switch, pin and cable. This is the easiest way to replace a breakaway pin is replacing the switch and pin all together as the switches themselves are all universal but matching the pins can be a bit harder. For just the pin of this system we have the # HM20051...

  • Replacement Solenoid and Breakaway Switch for Roadmaster BrakeMaster Systems
  • We do have the 3-Way Mac valve solenoid for the BrakeMaster braking systems which does sound like the issue. It is # RM-450420. For the switch you can use any breakaway switch such as # HM20010 as an example because all it does is complete a circuit once the pin is pulled.

  • How to Install an Aftermarket Breakaway Switch on the Demco Stay-IN-Play
  • The Hopkins Replacement Break-Away Switch part # HM20010 has a normally open circuit which means there will not be any current that passes through the breakaway switch while the pin is intact. Once the pin is pulled the circuit then becomes closed and power is able to pass through the switch and send power to the trailer brakes. It does not matter if you hook the blue wire on the switch to the blue wire on the Stay-IN-Play or the black wire on the switch to the blue wire on the Stay-IN-Play....

  • Replacement Cable And Pin For Hopkins Engager Break-Away System
  • I spoke with my contact at Hopkins about your Engager Break-Away system. They told me that there was a change to the pin about 3 or 4 years ago and the pin on the newer systems is actually shorter than the previous switches. If your break-away system is one of the newer models then part # HM20051 would work well for you. This is the 48 inch cable with the pin that attached to the break-away switch. If you have an older model with the longer pin, then part # HM20010 would be...

  • Does a Vehicle Being Flat Towed Need a Breakaway System
  • When flat towing a vehicle the supplemental braking system being used will have a specific breakaway switch that goes with it. Supplemental braking is required by law in most states so if you are not using one you will want to look into getting one. The breakaway switches will not work with vehicle brakes directly because they are hydraulic and the switches work with electric systems. If you have a braking system, let me know which one it is and I can explain how a breakaway system gets...

  • Replacing Break Away Switch Used with Brake Buddy Classic Flat Towing Braking System
  • According to my contact at Hopkins Manufacturing, the # HM20010 break away switch you referenced would be a good choice to replace your damaged breakaway switch. Make sure that your connections to the existing wiring are protected from the elements using heat shrink tubing or electrical tape.

  • Will a Hopkins Breakaway Switch Work with a BrakeBuddy Braking System
  • A breakaway switch is a very basic device so you can use switch # HM20010 with your braking system. But I recently learned that the BrakeBuddy switches use banana clips to connect to the BrakeBuddy itself. To use this switch you would need to obtain those clips from an electrical supply store. Likewise, the coiled cable, # RM-8603, can be used on any system that has a loop in the breakaway cable that it can attach to so it will work with # HM20010.

  • Can Breakaway System of Trailer be Used as Parking Brake
  • If you pull the breakaway pin on your trailer it will lock the brakes up until the battery is drained. Breakaway kits shouldn't be used as parking brakes. You'd need a chock like the part # MT70073.

  • Hopkins Trailer Breakaway Kit Recommendation for Gooseneck Trailer
  • I'd recommend the Hopkins Engager, Side Load Breakaway kit, # 20099. The Engager has a push-to-test battery feature that lets you check your battery easily before each trip. It includes the 12-Volt rechargeable battery and has a lockable lid. I spoke to my contact at Hopkins and they do not offer any kits with part numbers 20100 or 20019. But, they do offer a # HM20010 and # HM20014, which are replacement switches but do not include the battery. If the breakaway system on your gooseneck...

  • 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.

  • Replacement Breakaway Switch or Pin For Trailer
  • The plunger can be put back in place without any other functions needed to reassemble. In fact, that is exactly how you test the system for function. If the pin is not able to be put back in place so that the brakes don't lock up, then you can simply disconnect the breakaway battery. As long as there is no power going through the system the brakes will only be active when there is power from the trailer brake controller. If the way the system was wired, makes the system lock the...

  • Breakaway Switch Recommendation to Replace a Bargman Breakaway on a 1976 Nomad Trailer
  • The Bargman breakaway switch that you have is still sold to this day. Basically, you can use any breakaway switch that you would like. They are a very simple device. Once the pin is pulled it completes the circuit from the breakaway battery and the trailer brakes which applies the trailer brakes. What I recommend is a system that comes with a charger. Take a look at the Engager Trailer BreakAway Kit, # 20099. This is our most popular kit. It comes with the switch, a battery, a box, charger,...

  • Replacing the Blue Ox BrakeBuddy Break-Away Switch with the Hopkins Replacement Break-Away Switch
  • The Blue wire on the Hopkins Replacement Break-Away Switch # HM20010 will need to be spliced to the wire that sends the signal for the braking on your Jeep. The Black wire will need to be connected to your BrakeBuddy. I recommend using Heat Shrink Butt Connectors # DW05745-5 to make your splice and connection. You will also want to secure those connection points using Deka Self-Fusing Auto Tape # DW04367. Both of these used together will do an excellent job at protecting these points...

  • Replacement Breakaway Pin and Switch Recommendation for a Lost Pin
  • The easiest option you have that would make the most sense would be just to replace the switch and plug of your system. Especially considering how inexpensive they are. I would recommend you get the # HM20010. This will wire in to your system exactly your old one will and will provide you with a new switch and plug that will eliminate any guess work. Based on the picture you submitted the part # HM20012 would be too long to work as a replacement.

  • Replacement Pin for an LBS48-16 ESCO Break Away Switch
  • While we do have numerous replacement break away system pins, all of which are similar, I cannot guarantee that any will fit your ESCO brand switch because they have not all been tested together. The difference in cost between a replacement pin and a new switch is minimal so I advise just replacing the switch with # HM20010.

  • Replacement Parts For Older Model Hopkins Engager Breakaway Kit
  • The Hopkins Engager's box design and mounting brackets have changed over the years. There is a Side load Hopkins Engager available and a top load style. The Hopkins Engager part # 20400 is considered top load because you can see the lid from the top of the unit but the brackets do not allow you to install the box upright on the trailer's tongue like in your photo. The old style entire unit is no longer available but the replacement box part # HM20121 is available and can be installed...

  • Replacement Trailer Breakaway Switch Recommendation with 7 Feet of Wiring
  • We have the Hopking breakaway switch part # HM20010 that has 7 feet of lead wires that comes with it. Since that's the length you need it wouldn't require you to splice in additional wiring. This has 12 gauge wire as well.

  • How Does a Break Away Battery Charger Wire Into a Trailer Break Away System
  • A break away switch, like # HM20010, has a pin it that when pulled out completes a circuit from the battery mounted on the trailer to the trailer brakes. This allows the battery to apply voltage to the trailer brakes to stop the trailer should it become disconnected from the tow vehicle. The charger, # 20011, receives 12 volt power from the tow vehicle on the black wire. It sends this power to the break away battery on the trailer to provide a maintenance charge along the red wire. The...

  • How Much Force does it Take to Pull the Pin on a Break-Away Kit Switch
  • It is a simple switch, so brand compatibility should be a non-issue. When the pin is pulled, two pins are allowed to contact and complete the circuit to engage the brakes. Any switch should work fine. I pulled the Hopkins Switch, part # HM20010, to test it out. It does take a good tug to pull it out and close the switch. You should not need to use two hands, but it should not easily slide out. You do not want the pin coming out when you hit a hard bump. I would not repeatedly pull...

  • Replacement Breakaway Pin & Cable for Hopkins Break-Away Switch HM20010
  • If you are referring to the pin for a breakaway kit like # HM20010 that you referenced we do sell a pin and cable on its own as part # HM20051. This replacement pin/cable works with many Hopkins breakaway kits, all of which are listed on the page for part # HM20051.

  • Troubleshooting Trailer that Has Locked Up Brakes After Disconnected from Trailer
  • I attached a help article that details how to test a breakaway system, but basically it sounds like your breakaway switch has gone bad or the pin of it has partially unplugged itself so your system is locking up the brakes. If you cut the wire leading to or from the breakaway switch itself the brakes should release. For a replacement switch that would fit nearly all systems you would want the # 2005-P. To pick out the correct brake assemblies for your trailer you need to know a few...

  • 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...

  • What to Do About Missing Breakaway Switch Pin if You Don't Know the Manufacturer
  • Not all pins are created equally but all breakaway switches are pretty much the same. Since we can't determine for sure which system you have I recommend replacing the whole switch with # HM20010. The only thing in the switch are 2 metal contacts that are kept separated by the plastic pin. When the pin is pulled the contacts can touch and complete the circuit from the battery to the brakes. That is why you can use a different switch. It is a very basic system!
