Could be, there is an insulator in there next to it. Maybe it's disintegrated or misplaced? I think it basically is operated by "bending" a flat metal contact. Maybe you did find the problem. I may also be remembering it wrong. Maybe this is cheap enough to try fix by replacement. That is always a good move depending on price. Certain parts are old, suspect, cheap and good to eliminate as the problem. Expensive parts take a different approach. The stomp switch is easy enough to test with continuity tester if you want. Operate it over and over and over while testing.

Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
