Relays are common electromechanical devices in electrical circuits that come in two types: either latched or non-latched. Latched relays retain their last switch position even after complete power ...

Single-coil latching relays, whose applications include signal routing, audio, and automotive systems, can pose a design challenge because coil current must flow in both directions through a single ...

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 ...

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.

Knowing the sequence of operation for this type of starting relay can help you diagnose, confirm, or rule out certain service problems. Potential starting relays consist of a high resistance coil and ...

Many varieties of ON/OFF control circuits use some form of flip-flop that responds to a pushbutton switch or other control input. These all have volatile memory and default to an OFF condition if ...
