What is a relay? What is zero voltage switching? How to create a zero-crossing relay driver with a simple external circuit. A relay is a device that allows for a smaller electronic switch to ...

This low current relay circuit is designed to be used in battery operated electronic devices. Its operating current is in micro amperes (µA). This is done by using a bistable relay and adding some ...

This makes a great XOR circuit–think about it. It is even more straightforward to create XOR if you don’t mind using two relays. Many modern demonstration relay computers bite the bullet and ...

In critical industrial and commercial systems, downtime is not merely inconvenient; it is costly. For operations that depend ...

Designers frequently use special circuits to reduce the power required to hold a relay in the latched position. Analog circuits such as the "brute force" resistor-capacitor solution or the time ...
