Video Transcript for Curt Trailer Breakaway Kit C52010 Review

Speaker 1: Today we're going to take a look at the replacement switch for the Curt Softrack One and Softrack Two Trailer Breakaway kits. Now a breakaway system will activate your trailer's electric brakes if the trailer disconnects from the two vehicle. This part here is the breakaway switch, this will replace the switch that came with your breakaway kit. This part here is designed to work with the Curt Softrack One, which is part number C52040 or C52041 and also the Curt Softrack Two, part number C52028 or C52026 Breakaway Kits. All those kits we do sell separately on our website.Now this will include the cable and the pull pin. If you notice the breakaway switch is on this weldable, high temperature metal mounting tab.

Does use silver contact points. It's all in a nylon case and the pull pin. Now basically the breakaway switch will install on your trailer frame. The wiring right here would wire into the rest of the wiring on the trailer, and then you'll have this cable that connects to the pin. Your pin's right here and there's your cable.

The other end of this cable right here is what would connect to your two vehicle so that if the trailer and the two vehicle ever disconnect, it'll pull that cable, which will then pull that pin out and that'll activate the brakes and bring your trailer to an eventual stop.But that should do it for the review on the replacement switch for the Curt Softrack One and Softrack Two Trailer Breakaway kits.

I ordered two items, and soon after, received an update that my delivery date was about a month out. Shortly after that, I received a message from George J stating that one of the items was on back order, and if I liked, they could send the other item right away. I have an upcoming camping trip and the non back-ordered item, the one I most wanted, was the one that was available. Still, I thought that with the shipping issues I am dealing with for clients as a general contractor, the item would still not arrive in time for the trip. To my pleasant surprise, today I received an email from Carol C letting me know that my shipment had been delivered. I expected the one item, but ended up finding both had arrived. The camping trip is this weekend, so because of great service, I have the new products in plenty of time! Thank You, Greg


I selected this breakaway safety switch since it appeared to be dimensionally similar to the original one. I completely replaced the brake system (electrical and mechanical) on our 2013 travel trailer, and discovered during measured testing that the original switch contacts were no longer functioning as required. I've installed the new switch, and it was indeed identical to the original OEM unit. The only reasons that I didn't give it 5 stars is that (1) the plating on the metal frame appears that it will be prone to rust excessively just as the original one, and (2) there's no instructions provided on how to effectively (and safely) shorten the pull cable so that it won't hang down too low yet not be too tight and causing an unwanted trailer brake activation.


Applied breakaway switch to wire loop bolt, due to mounting bolt for base plate of switch was sheared off due to rust. Wires attached to original wiring and shrink-wrapped. Will not know if it works until I have a near disaster!!!


Exact replacement. Hardest part was refitting the quick connects that came with my trailer. All done in 10 minutes. Meter (voltage) test plug in/out -- good. Road test -- good.


The bracket on my old switch was rotting away, which in the event of a break away would deem useless. This was a very cost effective replacement and came with everything necessary.


Went to 4 local trailer dealers/manufacture facilities looking for battery box and breakaway kit. All I found was box/battery/switch/tester unit for [3 times the price], found and found exactly what I was looking for, [price] bucks and the items are quality.


Perfect fit


As this is an emergency product, I have not tried it out. The shipment time on the order was very slow but the product was what I ordered


Quality product at fair price. Replaced Oem part with no modifications.


This is the standard I use on all my trailers. I have never had an issue with one of these, except the time I ran over the "key" with my lawn mower and chewed it up. That was an easy replacement from another trailer because they are all alike.


I've been using this with my brake away on my horse trailer for over a year and it has held up very nicely. I've had no problems and am very happy with this product.


I've ordered from etrailer previously and have always gotten good service at good prices. Very satisfied, once again. I also appreciate the videos that etrailer provides as assistance for those of us who always need assistance! I'm sure I'll be back again when I need rv parts.




Easy to install and fits the trailer very well


Exact replacement for my trailer and great product, thanks for following up


I already had a battery in my trailer for a winch. This is all i needed to have a functional breakaway system. Easy install, 1 wire to 12V+ 1 wire to brakes


Very nice switch, easy to install.


This product replaced one that was not in stock. Thanks for the quick follow up and replacement. I needed it to get my Toad back behind the MH.


Same product as the old factory module
delivery and excellent people to work with


Great products fast shipping .... Will buy from you again


Works great! Wiring was plenty long for an easy install.


tow set up for our CRV installed nicely easy connect and disconnect .Love the all terrain hitch towbar assembly can hook the car up all by myself now


Exactly what I ordered. Great service.


Easy straight forward install. Along with getting item quickly from, great site and service as always.


Seams to work fine, luckily haven't had to!!!

Ask the Experts about this CURT Accessories and Parts

  • Trailer Breakaway Switch Wiring Functions
    If the breakaway system has a charger then the 12 volt circuit from the trailer connector will go to it. Otherwise it goes to the breakaway battery. The breakaway switch will have one wire that goes to the brake magnets and the other to the breakaway battery. I have linked a help article on breakaway systems for you.

  • Can I Use Curt Replacement Breakaway Switch With TAP Breakaway System
    The TAP breakaway system is actually the same as the Hopkins Engager Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger part # 20400. You can use the Replacement Switch for Curt Soft Trac I and II Trailer Breakaway Kits part # C52010 with the TAP system. The two blue wires from the Curt switch will splice into the blue wire from the breakaway box and the other blue wire splices into the electric brake wire of the trailer. I have attached a diagram for your reference.

  • Is a Breakaway Switch Normally Open or Closed
    If the pin on the breakaway switch is pulled or broken then yes you should have 12 volts entering and exiting the switch as this is what will engage the brakes on the trailer. The breakaway switch on your trailer is a normally open circuit which means power will not pass through the switch if the pin is installed and functioning properly. It is possible that the switch has failed so if you need to replace it you can do so with pretty much any brand like the Replacement Switch part # C52010....

  • Solution for Needing New Trailer Breakaway Switch Pin
    When in need of a replacement breakaway cable the easiest solution is to just replace the switch and cable since it really hard to identify the switch manufacturer. And also the switch and pin assemblies are universal to other brands since it's just two wires. So in that case the Curt switch replacement # C52010 is a really easy and cost effective solution. You'll wire the blue wires to what you have on your trailer now and you'd be set with an all new setup.

  • Easy Solution for Damaged Breakaway Cable on Trailer
    The easiest solution is a new breakaway switch with the Curt # C52010. Since all of the switches operate using the same mechanism you can easily replace the entire switch with something like the Curt I mentioned regardless of the brand of the breakaway kit. Trying to replace just the pin of a switch you may have does get tricky though as that would require determining which exact breakaway kit you have.
