A few things to be aware of when experiencing problems and before replacing the switch.
1. is the current switch in tight? I've seen them back out 1/4 turn and then fail to work.
2. Has the switch been removed and reinstalled? Did the steel ball bearing fall out? When you remove the switch there is a ball bearing that is in the hole that the switch goes in.
3. I've seen some switches that mount with a washer. If the switch becomes warn and intermittent chances are the plunger is not going in far enough. Remove the washer and reinstall the switch.
