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 ...

Electroswitch control switch relays (CSR) combine the function of a control switch with a remote-controlled solenoid, allowing one device to do both the manual and supervisory control function in the ...

Electromechanical relays (EMR) and reed relays have served automated test equipment (ATE) applications well, but they’re not likely to satisfy their needs in the future, as ATE manufacturers strive to ...
