Solid State Switch Symbol. Solid state semiconductor. Normally open switch symbol switches and relays vector stencils library design elements.
Relay symbols and electromagnets. The mechanism of a switch may be operated directly by a human operator to control a circuit for example a light switch or a keyboard button may be operated by a moving object such as a door operated switch or may be. Unlike emr electromagnetic relay that has a coil mechanical switch physical contacts the ssr relay uses optocoupler to isolate the control circuit from the controlled circuit.
Solid state relay ssr is an electronic switching device made of semiconductors that switch on off a high voltage circuit using a low voltage at its control terminals.
It has no moving or mechanical parts so they have more lifespan as the mechanical contacts wear out with switching. Auto switches are used for end of stroke sensing for actuators. Various lead wire lengths are available. Normally open switch symbol switches and relays vector stencils library design elements.
