    Answer:

    SPST-2

    Explanation:

    The terms post and pull are also used to describe the contact variations of the switch. The number of “poles” is the number of electrically separated switches that are controlled by a single physical actuator.

    For example,

    The “SPST” switch is single-pole, single-throw, a simple on / off switch: the two terminals are connected or disconnected from each other.

    The “SPDT” switch is single pole, double throw, a simple interrupt changeover switch before making: C (COM, Common) is connected to L1 (NC, normally closed) or L2 (NO, normally open).

    “DPST” is bipolar, single shot, equivalent to two SPST switches controlled by one circuit.

    “DPDT” is bipolar, double throw, equivalent to two SPDT switches controlled by two circuits.

    “3PDT” is 3 pole, double throw, equivalent to 3 SP and DT switches controlled by two circuits.
