I suppose that I should have made clear: these announcer boxes are=20 desktop units. They aren't the Ref Mic switches that I also=20 make. One style of those also uses toggle switches but they are far=20 enough away from the mic that the noise simply isn't a problem (the=20 switch is mounted on the Ref's belt, on his side and the mic is=20 either a lav located on his upper chest *or* is a headset mic). >Bur, if you're gong to disassemble the switch, why not put a couple of to9= 2 >hall effects in instead of a flag?

I'm actually trying to eliminate any metal-on-metal contact at the=20 end-stops. That's where the 'snick' / 'snap' sound is currently coming fro= m. The advantage of the friction pad is that the toggle lever will stay=20 put wherever it is placed. The reason for using two sensors (one at=20 each end) is to eliminate any ambiguity if the switch is moved to the=20 center position. Its worth a try, anyway.
