I have 4 "3 way" toggles in my A/S
One set for the galley light ( door way and at the sink) and one set for the
pump
( at control panel and in the bathroom)!
I tried to pull one to see how many terminals but am afraid to disturb
something that's been there for 30 years!
Any household 3way switch has 3 terminals
with the 3rd one being the COMMON wire, the wiring for 110v or 12v should be
typical.
