I have a faulty microswitch in a PA pr16 pressure switch. Anyone know the exact model of microswitch? There is no part number on it. PA says its an in house p/n 12.5001.00. You can get a single switch online from electrical suppliers for like $3.00 but there are a few variables that I don't know(different ratings, actuation tolerances, etc). No need to pay $20 extra bucks for the housing and wires unless I have too:haha:
