Thanks for the info mate,
I am using a Sigma SIGAC05 timer to trigger two 5 pin relays.
It works great when I trigger the timer(by either touching it to an earth or feed, depending on which polarity i need to use),my problem is however, triggering the timer from the alarms Green/Orange wire(the one that supplies power to the microwave). It doesn't have enough current to switch it over!!!
Did you need to use a transistor?
