Manufacturer wanted $25 (+shipping) for a replacement garage door opener wall switch. 13 minutes of printing + 5 minutes of soldering + two leftover Cherry MX Blue switches (that I’ll be use) and the problem is solved 👍
Note: The wiring was slightly more involved than I thought… needed a resistor for the light (there’s only two wires but it’s got two functions: Light on/off and garage open/close.
If folks are interested I could make a much fancier PCB-based version with screw terminals and whatnot. It’s a very trivial schematic.
Very resourceful, I like it.
Added benefit: you’ll definitely hear it if someone tries to open the garage door and steal all your stuff in the middle of the night
