I'm on the lookout for a cheap but reliable tactile SPST momentary push button key. Switching requirement is of the order of micro-amps, since it would be interfaced with a microprocessor. The application is a device to be used in Automobile. And the switch could be pressed on an average 10 times a day.
- approximate price target is USD 0.1
- size should be small like 5 to 7 mm dia
- temperature would be less than 70 deg, but operating relative humidity could go up to a maximum say, 80%
- it should be able to withstand "repetitive-hard-press" abuse from say, a kid (do I remember someone!).
Any hints? Mike
