Video Transcript for Demco SMI Supplemental Braking System Replacement Breakaway Switch Pin Review

Jake: Hey, guys. It's Jake here with etrailer. Today we're going to be taking a look at the replacement pin for your SMI braking system.In our case here, we had a customer who had a breakaway, and the tow vehicle had separated from the towed vehicle, and he lost the breakaway pin. So, he's picking up a new one. To replace this, you just slide it back in and replace your cable. This is very important to have, because otherwise, your system's not going to work.You want to make sure you keep your pin in good condition, so whether that's you've lost one, you've broken one, or it's just gotten older and brittle and you need to replace it.

It's a simple and small enough part to keep on hand for those longer trips, so you might want to go ahead and pick up a couple of them when you get your system or when you get a replacement.Then of course before you leave, you want to make sure you hook up your safety cable and you're ready to hit the road. With that being said, that's going to do it for our look and installation of our SMI replacement pin.

I was advised to have a back up Breakaway Switch Pin for our Air Force One braking system. This pin works perfect and I will keep it with the car in the event the present one gets damaged or loss. etrailer sent it out quickly and now I have a backup to keep in our tow car. I would recommend getting a back up pin.

The product is excellent! I found etrailer to order a spare. The process was easy and quick. I received updates on my order throughout the process. I recommend etrailer.

It is the standard breakaway switch.

Works as it should. You dont need to have it installed to drive the tow vehicle, if you turn off the Stay N play system.

Great Product, we have a spare at all times, lucky we have never had to use the spare, products works great.

I ordered an extra breakaway pin to keep as back up after installing a Demco Stay-in-play brake system I am very pleased with the Demco brake system and also with the prompt and accurate service provided by etralier.com in providing the breakaway pin. Great service. Thanks.

Wanted to have a spare since this is an essential part of my safe towing/braking package.

Purchased as a spare, fits my original breakaway switch.

Identical to the one we have. bought extra one incase ours gets taken. Thank you for having his part the installation company could not order a spare for us.

Excellent well made product but it has to be installed to drive the tow vehicle on its own (unless you want to pull fuses). Personally I cut off the very noticeable wire and change it to a smaller ring that brings less attention to curious eyes & fingers. You must change back to the one with the wire loop when in the two mode for safety reasons. Keep a spare in the glove box just in case!

The picture was very clear and allowed me to identify this pin as the one I needed. I purchased two for a backup. Because it sticks out of the front of the car, it looks too tempting for a child to walk by and pull it out. It was exactly what I needed


Comments
Still working and intact after thousands of miles.

Exactly like original!

The product is a perfect match for the stay and play braking system. Like everyone else I was apprehensive at someone stealing the unsecured original and leaving us without brakes. I’m not thrilled that if it does get stolen and the toggle switch inside the side gets accidentally turned on the brakes will fully apply. Seems a liability so having a back up makes sense to me and most everyone else.


Comments
Update: if your tow car has a standard transmission with hill brake assist do not adjust so much that the hill brake assist comes on. It doesn’t release quickly enough and your tow car brakes will lock up for a scary second or two

Just what I needed to keep my trailer on the road!

Part fit well on my Blue Ox breakaway switch. I tested to see if worked. Performed as designed. The cable attachment looks kind of funky. I replaced it with a small clevis.

Fine

I purchased the Replacement Breakaway Switch pin in the event the primary one get lost or damaged. If this pin is lost, you system will not function safely in the event of a emergency disconnect. Its good to have extras on hand. well worth the purchase from Etrailer.

Timely. Exactly what I needed. Hard to find on other sites.

Thank you etrailer, this replacement key fit and works perfectly, like the original.

I felt the loop on my existing breakaway switch hanging on the front of my car was too much temptation for a kid to pull it and take off with it, so I decided I should carry a spare. Tried it and it seems to work. I couldn't find a replacement anywhere other than etrailer!

I always carry a spare plunger for my break away switch.
