Double Pole Double Throw Switch. A double pole double throw dpdt switch is a switch that has 2 inputs and 4 outputs. Sp and dp refer to single pole and double pole st and dt refer to single throw and double throw. You can see above how a double pole double throw switch can allow a circuit to be in 1 of 2 modes.
Dp switches control two independent circuits and act like two identical switches that are mechanically linked. A double pole double throw dpdt switch is a switch that has 2 inputs and 4 outputs.
Each input has 2 corresponding outputs that it can connect to.
You can see above how a double pole double throw switch can allow a circuit to be in 1 of 2 modes. Dp switches control two independent circuits and act like two identical switches that are mechanically linked. A double pole double throw dpdt switch is a three selection electrical device in which there is one off and two on positions. An application for this switch is for reversing a direct current dc electrical motor.
