A rocker switch is a type of switch that is commonly used in various electrical applications. A double pole double throw (DPDT) rocker switch is one that has two positions and can be used to control two circuits simultaneously. In this article, we will discuss how to wire a DPDT rocker switch and provide a wiring diagram for easy reference.
What is a DPDT Rocker Switch?
A DPDT rocker switch is a switch that has two positions, and each position is connected to two poles. This means that a DPDT rocker switch can control two circuits at the same time. The switch has six terminals: two for the input, two for the output in one position and two for the output in the other position.
DPDT rocker switches are commonly used in various applications that require the switching of two circuits simultaneously. Examples include audio equipment, automotive applications, and industrial equipment.
How to Wire a DPDT Rocker Switch
Wiring a DPDT rocker switch is not difficult, but it is important to follow the proper wiring diagram to ensure that the switch functions as intended. Below is a step-by-step guide on how to wire a DPDT rocker switch:
Step 1: Gather Materials
Before you begin wiring your DPDT rocker switch, you will need to gather the necessary materials. These materials include:
| Materials | Quantity |
|---|---|
| DPDT rocker switch | 1 |
| Wire strippers | 1 |
| Electrical tape | 1 roll |
| Wire connectors | 4 |
| Wire | As needed |
Step 2: Identify the Terminals
Once you have gathered all the necessary materials, you will need to identify the terminals on the DPDT rocker switch. As we mentioned earlier, the switch has six terminals: two for the input, two for the output in one position and two for the output in the other position.
The terminals are typically labeled or numbered, so make sure to take note of which terminal is which.
Step 3: Strip the Wires
Using your wire strippers, strip the ends of the wires that will be connected to the DPDT rocker switch. Make sure to strip only the necessary amount of wire to avoid any unnecessary exposure.
Step 4: Connect the Wires
Using your wire connectors, connect the wires to their corresponding terminals on the DPDT rocker switch. Refer to the wiring diagram below for the proper connections. Make sure to double-check each connection to ensure that it is properly secured.
DPDT Rocker Switch Wiring Diagram
Below is a wiring diagram for a DPDT rocker switch:
As you can see in the diagram, the input is connected to terminals 2 and 5, while the output in one position is connected to terminals 1 and 4, and the output in the other position is connected to terminals 3 and 6.
FAQs
What is the difference between a SPDT and a DPDT rocker switch?
A single pole double throw (SPDT) rocker switch is a switch that has two positions and can control one circuit. A DPDT rocker switch, on the other hand, has two positions and can control two circuits simultaneously.
What are some applications that use DPDT rocker switches?
DPDT rocker switches are commonly used in audio equipment, automotive applications, and industrial equipment.
What should I do if I am unsure about how to wire a DPDT rocker switch?
If you are unsure about how to wire a DPDT rocker switch, it is best to consult a professional electrician or refer to the manufacturer’s instructions.
