Wiring a single pole double throw switch. A double pole single throw dpst switch controls the connections to two wires at once where each wire only has one possible connection. A single throw switch is a simple onoff switch that connects or disconnects two terminals. The number of throws indicates how many different output connections each switch pole can connect its input to.
