Touch ON OFF switch circuit diagram using IC 4017

A toggle switch can use to ON and OFF the load alternatively with the incoming pulses. That is, to act as a push ON and push OFF switch. The circuit uses a decade counter IC...


Piezoelectric sensor toggle touch switch

In this touch switch, a piezoelectric sensor is used to sense the touch action. It can generate an electrical charge from any change in physical parameters such as pressure, strain, force, acceleration and temperature.  A...


Non contact AC voltage detector circuit

A non-contact AC detector is an easy and safe AC live line tester. It can detect electricity in a conductor without any physical contact. The device can indicate as it reaches near to a...
