Double Pole toggle switch is a type of switch that is commonly used in electrical circuits to control the flow of electricity. It is also known as DPST or Double pole, Single Throw switch. This type of switch is often used in circuits where there is a need to switch two lines simultaneously, such as in lighting circuits, motor controls, and similar applications. In this article, we will discuss the wiring diagram for double pole toggle switch and how to use it in different applications.
What is Double Pole Toggle Switch?
A double pole toggle switch is a switch that has two separate circuits that can be controlled by the same switch. Each circuit has its own set of contacts that can be opened or closed independently of the other circuit. This type of switch is commonly used in circuits where there is a need to switch two lines simultaneously, such as in lighting circuits, motor controls, and similar applications. The switch has a toggle lever that can be used to control the flow of electricity.
The double pole toggle switch is available in different sizes and configurations. It can be rated for different voltage and current levels depending on the application. The switch can be made from different materials such as plastic or metal, depending on the environment in which it will be used.
Wiring Diagram for Double Pole Toggle Switch
The wiring diagram for a double pole toggle switch is relatively simple. The switch has four terminals, which are usually labeled as follows:
- Line 1 – this is the first line that needs to be switched.
- Line 2 – this is the second line that needs to be switched.
- Load 1 – this is the first load that needs to be switched.
- Load 2 – this is the second load that needs to be switched.
The wiring diagram for the switch is as follows:
| Terminal | Function | Wire Color |
| Line 1 | Switched Line 1 | Black |
| Line 2 | Switched Line 2 | Red |
| Load 1 | Load 1 | White |
| Load 2 | Load 2 | Gray |
The black and red wires are the lines that need to be switched. These wires should be connected to the Line 1 and Line 2 terminals respectively. The white and gray wires are the loads that need to be switched. These wires should be connected to the Load 1 and Load 2 terminals respectively. Once the wires are connected, the switch can be used to control the flow of electricity between the lines and loads.
Applications of Double Pole Toggle Switch
The double pole toggle switch can be used in different applications where there is a need to switch two lines simultaneously. Some of the common applications of the switch are:
- Lighting circuits – The switch can be used to control the flow of electricity between two separate lighting circuits.
- Motors – The switch can be used to control the direction of the motor by switching the two power lines.
- Heaters – The switch can be used to control the temperature of a heater by switching the two power lines.
FAQs
Q: Can a double pole toggle switch be used in a 120V circuit?
A: Yes, a double pole toggle switch can be used in a 120V circuit. However, the switch should be rated for the appropriate voltage and current levels.
Q: How do I know which wire is Line 1 and Line 2?
A: The wires can be identified using a voltage tester. Line 1 will have voltage when tested against ground, while Line 2 will have voltage when tested against Line 1.
Q: Can a double pole toggle switch be used for DC circuits?
A: Yes, a double pole toggle switch can be used for DC circuits. However, the switch should be rated for the appropriate voltage and current levels.
Q: Can a double pole toggle switch be used for three-way circuits?
A: No, a double pole toggle switch cannot be used for three-way circuits. For three-way circuits, a special switch called a three-way switch is required.
