This application note presents different types of overvoltage protection devices for solid-state relays. The document also provides suggested recommendations on their selection and use with the Vishay ...

Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...

What is an automotive relay? In simple terms, an automotive relay is a small cube shaped electronically operated electromechanical switch. It uses an electromagnetic device to mechanically maneuver a ...

The addition of a components and an unused NC contact to a dc supply provides a power-reducing feature to a relay driver circuit. Electromagnetic relays need much less power for holding than they do ...

Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.
