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 ...

Some make and break loads, while others only carry current ... The type of circuit load is an important factor in selecting the proper relay. Circuit loads can generally be considered capacitive, ...

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 ...

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 ...

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 ...
