How to solder Remotec Dry Contact Switch to Garage Door Opener



Here is a picture of the circuit board of my garage control remote. How/where exactly would I solder speaker wire to it so that I can hook it up to this Remotec Dry Contact Switch. I see these four lead points that the button has on the back side…which one or ones should I solder the two wires to? I’m trying to do something like this Instructable.

You should be able to test across the leads and figure out which ones to use

Despite having 4 pins on the back there are only two for you to connect to since two of them are connected together.


Yep - I took a piece of jump wire and shorted the contacts and found out which one. Thanks, guys.
