Coil Suppression Can Reduce Relay Life This application note deals with problems related to the methods used in deenergizing electromagnetic relay coils, particularly when a solid state switch is used, and how they affect relay life

Contact Arc Phenomenon Contact Arc Phenomenon, What precisely is an electric arc? How does it ignite and what causes it to extinguish? How does an arc affect the life of relay contacts? pdf file

Contact bounce and de-bouncing contact bounce and de-bouncing, push-button switches, toggle switches, and electro-mechanical relays all have one thing in common: contacts. It's the metal contacts that make and break the circuit and carry the current in switches and relays

Electromechanical relays relays are extremely useful when we have a need to control a large amount of current and/or voltage with a small electrical signal. The relay coil which produces the magnetic field may only consume fractions of a watt of power, while the contacts closed or opened by that magnetic field may be able to conduct hundreds of times that amount of power to a load

Relays

Relay contact life pdf file

Relays a relay is an electrically operated switch. Current flowing through the coil of the relay creates a magnetic field which attracts a lever and changes the switch contacts. The coil current can be on or off so relays have two switch positions

Relays a relay is used to isolate one electrical circuit from another. It allows a low current control circuit to make or break an electrically isolated high current circuit path
