Better than the original
When my stabilizing jack legs wouldn’t extend, I thought it was best to start by replacing the cheapest part in the system. When I removed four screws and looked at the switch that was originally installed, I couldn’t believe how cheaply-made it was. The new switch is sealed to protect the internal contacts and is made so much better. It is an easy install. The two larger wires run to the battery. The two narrow wires are for extend or retract. It’s that simple. Quality product.

Better than original.
So I am sure it also happened to you. You get to your camp site and you set up your trailer and you go to lower your stabilizers and snap, darn switch breaks. Yup. Sucks. It happened to me the second time but this time we were leaving. I went to bring them up but accidently went down and snap again. Good thing the retract function was still working. Switch was the original six year old switch. I just ordered two so I can keep one as a spare. I like these better than the original switches. These have a protector on them. Color coded as well. Nice.

Direct factory replacement
I bought this switch to replace what I believe to be a faulty switch on my 2017 Forrest River travel trailer. The exterior switch was not working for the levelers but the remote was working to control them. When I went to replace the switch I noticed that the wiring had been damaged, I fixed the damaged wiring and the original switch started working so I kept this as a backup.

Perfect replacement
Perfect replacement for stabilizer jack. Both of mine went limp at the same time, and these were a perfect replacement. If you're from Canada, look at purchasing them from the US site, because they're half the price.

Good value landing jack replacement
I liked the cover that protects the switch. The colour coding for the motor wiring was backwards for extend retract to my trailer. The original components I changed were Atwood products. It was easy enough to wire up. The switch wires were a 14AWG and the trailer wiring was 10AWG again not a huge issue just make sure you have a selection of inline connectors. Install was pretty easy with some basic tools wire stripper, crimper, connectors, and tape. I do the fact the back of the Lippert unit is sealed seems the contacts are more protected that way. I did modify the cut out slightly to make these fit the screw mounting holes did match up and there is a nice gasket that sits between the face of the switch and the trailer.

... 2 years old and it wasn't a covered switch like this one
The original switch was 2 years old and it wasn't a covered switch like this one, this one is far superior as it is waterproof.

Retract is Extend and Extend is Retract
The switch came as advertised. One problem is if you wire it bc up and color match all the wires. It is backwards. Retract is Extend and Extend is Retract. Easy way to fix this is get a black magic marker and black out the white lettering. Other than the mix up All Good
