I've ordered a replacment switch. I don't if someone messed with it or what. The "door" didn't close and it evidently got some crap down in it that keeps the key from going in far enough to operate. I tried vacuum, compressed air and WD40 with no luck. I never had trouble when I was using it in black dirt. But the sand where I use it now is a little more harsh environment (IMHO).Why do you need one? I had a Takeuchi TL130, never worried about covering the switch.
