How to clean kill switch?

[RedRover]

Sometimes the bike will turn over but not start until I flip the kill switch on and off a couple of times. I think I probably need to clean the switch but cannot figure out how to disassemble. Anybody else have this problem? Know how to clean switch?

You may not have to take it apart. Get an aerosol can of contact cleaner and blast it around the red bit. Work the switch a couple of times, and repeat. See if this works, before taking anything apart.
