I havea question of what this symbol means. I know its a switch, but does it mean normally closed with the + then when pressed it goes -? Its a three wire switch.
Relay or electronic switch? At least AFAIKS it seems that way.
The symbol on the bottom lead indicates a zero to potential transition (square wave). There's more to this than a simple switch, can you post more of the circuit or tell where it is being used?
