More Information on Power Relays...

What is a Power Relay?

A power relay is a switch which uses an electromagnetic coil in order to close or open a circuit. Power relays also contain an armature, a spring and one or several contacts. If the power relay is designed to normally be open, when power is applied, the electromagnet attracts the armature, which is then pulled in the coil’s direction until it reaches a contact, therefore closing the circuit. If the relay is designed to be normally closed, the electromagnetic coil pulls the armature away from the contact, therefore opening the circuit. Future Electronics carries the industry leaders in Electromechanical or power relays (Panasonic, formerly known as NAIS or Aromat, American Zettler, HongFa and Song Chuan.)
