Apologies upfront for this uber-noob question, but how should I wire a DPDT momentary footswitch to act like a regular SPST momentary? I guess I can forget about the second pole, but do I connect together one outer and middle lug or all three lugs together on the first pole?
The only reason I'm using the DPDT is they're smaller than the regular momentary switches, and I'm trying to fit two of them into a 1590A. It's pretty tight with the jacks.
You only need to use one pole, so ignore the second one. One side of each pole will be normally open and the other normally closed. If you have a continuity checker you can use that to see which is which. Or, just wire up the middle lug and one outer lug. If you get it backwards, switch to the other outer lug.
You can do more elaborate testing without a continuity checker but you have a 50/50 chance of being right the first time so why bother.
Great. Thanks Bean. :)
