This kit uses a touch plate to control the operation of a 555 timer and a 250V/12A relay. The switch operates to start a timer which can be set (by adjusting a fixed resistor and capacitor pair) to give delays from a few seconds to over an hour. The circuit operates from a +12Vdc@50mA power supply (not included).
