How to: Wiring a 2 pin rocker switch

A rocker switch is common used in the 4x4, vehicle, canopy and boating industry. A 2 pin rocker switch is a variation of this switch that has two pins, which can be wired in different configurations depending on the application. In this blog post, we will discuss how to wire a 2 pin rocker switch.
 

First, let's take a look at the pin layout of a 2-pin rocker switch. The pins are numbered 2 and 3 on the back of the switch. Here is a breakdown of each pin:

2: Power: This pin is where you connect the power source for the switch.

3: Output: This pin is the output for the switch. It can be used to control a device or circuit.
 

Now that we know the pin layout, let's talk about how to wire the switch. The wiring will vary depending on the application, but we will use a simple example to illustrate the process.
 

Let's say we want to use the switch to control a 12V LED light bar. Here's how we would wire the switch:

1.) Connect the power source for the switch to pin 2. In this case, we will connect a 12V power source from the vehicles battery.

2.) Connect pin 3 to a relay going to the LED light bar. This will be the output for the switch.
 

That's it! Now when the switch is turned on, it will supply power to the LED light bar. When the switch is turned off, power will be cut off to the LED light bar.
 

Remember, the wiring for a 2-pin rocker switch can vary depending on the application. Be sure to consult the switch's documentation or a wiring diagram before wiring the switch in your circuit.
