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 ...

The circuit utilizes the light sensing property of LDR ... Since this voltage level is lesser than the voltage at pin3, output of IC1 goes high to make the PNP transistor T1 off. Thus relay remains ...

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

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 ...

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 ...
