Double pole double throw switch wiring. Below is an example of a circuit which utilizes a double 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. Each input has 2 corresponding outputs that it can connect to. This allows the dc power to be reversed going to the electrical motor.
An application for this switch is for reversing a direct current dc electrical motor. A double pole double throw dpdt switch is a three selection electrical device in which there is one off and two on positions. When the dpdt switch is switched one way flipped upward in the diagram the lamp and buzzer are both on while the. A double pole double throw dpdt switch is a switch that has 2 inputs and 4 outputs.
This makes the the double pole double switch a very versatile switch. In this video i give you the characteristics of a dpdt switch and how to wire. The dpst switch often appears in circuit breakers where it is used for 240 volt circuits with each pole carrying 120 volts separately. This is how you wire a double pole double throw dpdt switch.
It can also be used at home to completely. This action then. In other words its like two simple switches controlled by a single actuator. 2 methods are explained with associated wiring diagrams.
The motors two power leads are reversed at one of the switches screw terminals.
