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 ...

When I think of economizer circuits for solenoids and relays, I’m reminded of the phrase, “you can’t have your cake and eat it, too.” This phrase comes to mind because if you use a solenoid economizer ...
