Didnt know what to title this as, im looking for something that requires a single quick pulse to activate a switch.
once the switch has been activated i dont want it to consume any more power so a relay is out, looked at thyrister but they require a continuous current to stay on.
the switch is connected to a timer, every 3 hours it sends a pulse, this will activate the switch, the switch is a double throw, i.e it has 2 outputs
so as an example i need it to do the following,
3 hours elapsed, pulse, switches to device A
3 hours elapsed, pulse, switches to device B
3 hours elapsed, pulse, switches to device A
anyone any ideas???
