DaierTek UP Down Momentary Reverse Polarity Switch 12V 30A DPDT Polarity Reversing Switch RV Power Jack for 5th Wheel Tongue Trailer Stabilizer

I was skeptical at first because it was so inexpensive but it worked great. And I have a spare switch!

is a good replacement dash switch for the tailgate window to replace OEM GM #14040844. It fits into the dash bezel and is the only one I could find with UP and Down Markings- they are not oriented vertically-but are easy to see. Sadly the terminal orientations are not the same so it wont just plug up.I made an adapter to test it. The hardest thing was getting the lengths of wire the same with the spade terminals correctly oriented to fit into the harness plug. You can always cut the harness and it will be easier, but was trying to avoid that for this test fit.I used 3 inches of 12 AWG Ancor tinned marine wire for each connection which is flexible enough and it will fit into the dash. I set the female terminals on the switch before orienting the males so I could make them all orient correctly. The harness plug fit is not as tight as I would like so will thinking about having my buddy make a bracket with his 3d printer. Another option might be to use hot melt glue to cement the male ends into a single plug. Tape will always work in a pinch.

I bought two switches that control the landing gear on my RV Fifth Wheel. The second one is a spare incase the switch needs replaced. While camping, the original switch failed to work. It was a simple installment of putting the current wires on the plug. It took five minutes to be up and running again, which saved having to do this manually. That pleased me! Delivery was on time.

This switch was a direct replacement for the factory original that went out. I couldn’t find the model number for the electric trailer jack to look up the switch, but measured the old switch to find a suitable replacement, and tried it. The only difference was that the terminals for the motor were reversed from the original, so you have a 50/50 chance of getting the polarity right the first time. Small issue, and only requires switching the terminals. It’s much better than the original switch. Highly recommended - picture shows the new switch.

Installed it the same day, everything worked.

Worked perfect

Came quickly. Reasonably priced

Fit my power jack perfectly and was really easy to swap out when my jack would go down but not up.
