DPST stands for Double Pole Single Throw. A rocker switch is a mechanical switch that is commonly used in various electronics and appliances. In this article, we will explain the wiring diagram of a DPST rocker switch.
What is a DPST Rocker Switch?
A DPST rocker switch is a type of rocker switch that has two poles and two positions. Each pole has a common terminal and two other terminals. The two positions are On and Off. When the switch is in the On position, both poles are connected to the terminals that are not common. When the switch is in the Off position, both poles are connected to their common terminals.
DPST Rocker Switch Wiring Diagram
The DPST rocker switch wiring diagram is quite simple. There are four terminals on the switch: two that are common and two that are not. Each pole has one common terminal and one not-common terminal. The wiring diagram is as follows:
| Terminal | Connection |
|---|---|
| Pole 1 Common | Connected to ground or negative |
| Pole 1 Not-Common | Connected to the positive of the load |
| Pole 2 Common | Connected to ground or negative |
| Pole 2 Not-Common | Connected to the positive of the load |

FAQ
What is the maximum current rating of a DPST rocker switch?
The current rating of a DPST rocker switch depends on the manufacturer and the model. It is important to check the datasheet of the switch before using it. In general, DPST rocker switches have a maximum current rating of around 10 to 15 amps.
Can I use a DPST rocker switch for AC voltage?
Yes, DPST rocker switches can be used for AC voltage. However, it is important to check the datasheet of the switch to ensure that it is rated for the AC voltage that you will be using.
How can I test if my DPST rocker switch is functioning properly?
You can test your DPST rocker switch using a multimeter. Set the multimeter to the continuity mode and check for continuity between the common terminals and the not-common terminals when the switch is in the On position. There should be continuity. When the switch is in the Off position, there should be no continuity between the common terminals and the not-common terminals.
Can I use a DPDT rocker switch instead of a DPST rocker switch?
No, you cannot use a DPDT rocker switch instead of a DPST rocker switch. DPDT stands for Double Pole Double Throw, which means that it has two poles and three positions. DPST switches have two poles and two positions, which is different from DPDT switches.
Where can I buy a DPST rocker switch?
DPST rocker switches are available in most electronics stores and online marketplaces, such as Amazon, eBay, and AliExpress. Make sure to check the specifications of the switch before purchasing.
Conclusion
A DPST rocker switch is a simple and reliable type of switch that can be used for various applications. The wiring diagram is easy to understand and can be used for both AC and DC voltage. Always check the datasheet of the switch before using it and make sure to test it for proper operation.
