Dpdt Switch Wiring Diagram

What is a DPDT Switch?

A DPDT switch (double pole, double throw) is a type of electrical switch that has two poles and two throws. This means that it can connect two circuits together or disconnect them. DPDT switches are often used in applications where it is necessary to control the flow of electricity to two different circuits at the same time. For example, a DPDT switch could be used to control the power to two lights in a room, or to turn on a fan and a heater at the same time.

DPDT Switch Wiring Diagram

The following diagram shows the basic wiring for a DPDT switch:

DPDT switch wiring diagram

As you can see from the diagram, a DPDT switch has three terminals: common, normally open (NO), and normally closed (NC). The common terminal is connected to the power source, and the NO and NC terminals are connected to the two circuits that the switch controls. When the switch is in the "on" position, the common terminal is connected to the NO terminal, and the NC terminal is disconnected. This means that the power is flowing to the circuit connected to the NO terminal. When the switch is in the "off" position, the common terminal is connected to the NC terminal, and the NO terminal is disconnected. This means that the power is flowing to the circuit connected to the NC terminal.

How to Use a DPDT Switch

DPDT switches are relatively easy to use. To turn on the circuit connected to the NO terminal, simply move the switch to the "on" position. To turn off the circuit connected to the NO terminal, move the switch to the "off" position. DPDT switches can be used in a variety of applications. Some common applications include: * Controlling the power to two lights in a room * Turning on a fan and a heater at the same time * Controlling the power to two motors * Switching between two audio sources

Conclusion

DPDT switches are a versatile type of electrical switch that can be used in a variety of applications. They are relatively easy to use and install, and they can provide a convenient way to control the flow of electricity to two different circuits at the same time.
