Hi, Can anyone suggest where I might be able to source a small number of the following items. I need an on-off panel switch, and also a button, which have to operate reliably for long periods despite possible contact degradation. It'll be single pole pulldown on a 5V logic line, with a pullup of maybe a few K (can't spare more than a couple of mA). There's no significantly higher voltage available as a sense supply. What I'm hoping is that one can obtain manual switches that use hall effect or something else 'static', so that there's no contact to get corroded or wear out. TIA
