What's a designer to do when challenged with a switching application that requires handling up to 70 kV? These applications are not as rare as one may think. In fact, a broad range of applications in ...

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 ...

Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.

This simple temperature relay circuit can be used to signal a fire or setpoint for temperature monitoring function. You need to adjust P1 so that T1’s base voltage is 0.5V smaller than the emitter ...
