A relay is an electronically operated switch that is remotely activated by an electromagnet which pulls a set of contacts to either make or break a circuit.  

Electrical relays are commonly used for switching signals, radio frequencies, high current circuits when using a lower current circuit, and loads such as resistive, motor, lamp, inductive, and capacitive applications. This is helpful when an in-line switch or existing circuit does not have the capacity to handle the required current.

 

At TE, we manufacture one of the broadest ranges of relay types, including latching (bi-stable) relays and non-latching (monostable) relays, plug-in relays, and reed relays. Our electromechanical relays are engineered for – among many other applications – electrical isolation, controlling power in manufacturing and transportation applications, and for switching smaller current values in a control circuit, such as in building automation technology and control panels. Relays serve as an amplifier.
