Electronic Toggle Switch

Description

This circuit is based on CMOS CD4013 Flip Flop IC. It has two stable states, ON and OFF. Once it is ON, it remains ON till you press the switch again. A short button press of a tactile switch SW1 latches the circuit ON and another toggles it back OFF.

Relay switch contacts can handle high AC Voltage as well as High DC current, this makes the project suitable for applications like ON/OFF Fan, Light, TV, Pump, DC Motor, any electronic project that require electronic toggle operations, and a few other devices work on AC voltage up to 250V AC or DC current up to 5Amps.

Applications: TV, Audio Equipment’s, Radio, Fan, Pump, DC Motor, Electronic Projects ON/OFF
