Flipping the switch gave no continuity either way. After flipping it back and forth several times, it began to make a high resistance contact.

Is there a switch with pretty high capacity that is on-on with push tabs that I could substitute? Bobby suggested some Honeywell switches but they are not on-on and don't accept the push tabs.
