Control applications often requirethat you set a relay latch in positionuntil you need it to change state.Latching relays accomplish that task.When you send them a pulse, they eitherremain in the ...

This circuit allows an SPST momentary pushbutton to act as a push-on push-off switch, using a DPDT latching (bi-stable) relay. It was originally intended to allow a single pushbutton switch on the ...

Most switching power-supply controllers provide non-latching fault protection. Satisfying a requirement for a latchoff response to a fault often requires the addition of excessive and redundant ...

Achieve max electric fuel pump output and safety using a relay plus an oil pressure safety switch. Achieving maximum output and safety with a custom-wired electric fuel pump requires a properly ...

Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...
