Cole Hersee on Toggle Switches

SPST   SPDT   DPST   DPDT

SP and DP refer to single pole and double pole. ST and DT refer to single throw and double throw. Pole refers to the number of circuits controlled by the switch: SP switches control only one electrical circuit, while DP switches control two independent circuits (and act like two identical switches that are independently linked). Don't confuse "pole" with "terminal." The DPST switch, for example, has four terminals, but it is a DP, not a 4P switch. Throw refers to the extreme position of the actuator. ST switches close a circuit at only one position. The other position of the handle is OFF. DT switches close a circuit in the Up position, as well as the Down position (ON-ON). A DT switch can also have a center position (frequently ON-OFF-ON).
