Circuit Board

This is a photograph of Toggle Switch No.1. It's a simple circuit that will energize and de-energize a relay at the push of a button. Only one half of the Cmos 4013 is used. So you could construct two independent toggle switches with a single IC. The circuit will work at anything from 5 to 15-volts. All you need do is select a relay with a coil voltage that suits your supply.
