inexpensive solid state NC switch with time delay?
i'm looking for a normally closed SPST relay type solid state device, that when current/voltage is applied to it's gate/trigger, it will:
1) open the load (turn it off)
2) keep it open while the current/voltage is applied to the gate at *around the same amount* of trigger current/voltage
3) keep it open for a few milliseconds after the gate/trigger current/voltage drops lower than the holding threshold.
4) after a that immediately closes the load again.
load voltage: ~6V
load current: ~500mA
... but it opens it, so i guess breakdown doesn't matter that much

go to your local computer store and get a pnp diode with heat-sink w/12 volt rating and your set GenoSource(s): carnal knowlege good luck Geno
