Much simpler circuits, though, are left at the mercy of a SPST switch; if you forget to turn a flashlight off, ... creating a very tiny auto off circuit for anything with an SPST switch.

CIT Relay & Switch’s UL/CUL-recognized VM3 snap-action switches offers a choice of a single-pole, single-throw (SPST) or single-pole, double-throw (SPDT) circuit.

The addition of an extra contact to an SPST switch lets it turn off one circuit and turn on another. This makes it a single-pole double-throw (SPDT) switch.

Electromechanical components including pushbutton switches, rocker switches, and illuminated tact switch buttons for power circuits and interfaces by Marquardt are available from TME. The components ...

Note: This rule applies only when the circuit breaker is used as the switch. If a general-use snap switch or contactor is used to control the lighting, this rule doesn't apply. UL 489, Standard for ...

Electronic circuits are represented by circuit diagrams, which use symbols to depict components like resistors, capacitors, and transistors. Input components, such as push-to-make switches ...

The MightyMUX high-performance analog switch line recently ushered in the ISL84521, ISL84522, and ISL84523 switches and their 10-nA maximum leakage currents. Such leakage currents ...
