    single pole, triple throw Similar to SPDT. Some suppliers use SPCO/SPTT for switches with a stable off position in the centre and SPDT for those without. Serial switch or two-circuit switch [citation needed] DPST (2P1T) Double pole, single throw: Double pole: Double pole: Equivalent to two SPST switches controlled by a single mechanism. DPDT ...

  3. Multiway switching - Wikipedia

    en.wikipedia.org/wiki/Multiway_switching

    These switches appear externally similar to single pole, single throw (SPST) switches, but have extra connections which allow a circuit to be controlled from multiple locations. Toggling the switch disconnects one "traveler" terminal and connects the other. Electrically, a typical "3-way" switch is a single pole, double throw (SPDT) switch. By ...

    Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...

  7. Automatic test switching - Wikipedia

    en.wikipedia.org/wiki/Automatic_test_switching

    Figure 1D illustrates a double-pole, double throw (DPDT) switch. Contact form, or simply form, is the term relay manufacturers use to describe a relay's contact configuration. "Form A” refers to a single-pole, normally open switch. "Form B" indicates a single-pole, normally closed switch, and "Form C" indicates a single-pole, double-throw switch.

  8. Relay - Wikipedia

    en.wikipedia.org/wiki/Relay

    SPST-NC (Single-Pole Single-Throw, Normally-Closed) relays have a single Form B or break contact. As with an SPST-NO relay, such a relay has four terminals in total. SPDT (Single-Pole Double-Throw) relays have a single set of Form C, break before make or transfer contacts. That is, a common terminal connects to either of two others, never ...

  9. RF switch - Wikipedia

    Single pole double throw (SPDT) switch from Agilent Technologies. Multiport switches or single pole, multiple throw (SPnT) switches allow a single input to multiple (three or more) output paths. Transfer switches or double pole, double throw (DPDT) switches can serve various purposes. Bypass switches insert or remove a test component from a ...
