  1. hi, i am after a VERY simple circuit to make a switch debouncer , using
    a toggle switch ( on/off )

    prefer something using something like bc548/bc558 transistors , etc.....
    i need to use it to toggle +5v to switch banks in eproms.

    Just a simple RC circuit might be all you need. You can also specify
    bounce free switches.

    It'll charge the cap very quickly when you close the switch, and
    when you open the switch it'll decay to about 1.6V in 1 second. If
    that's too slow, decrease the calue of the cap or the resistance of
    the resistor.
