How to: Wiring a 4 pin rocker switch

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

First, let's take a look at the pin layout of a 4 pin rocker switch. The pins are numbered 2 through 6. The pins are labeled on the back of the switch. Here is a breakdown of each pin:

2 and 5: Power: These pins are where you connect the power source for the switch.

3 and 6: Output: These pins are 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.

This is a Double Pole, Single Throw (DPST) switch. That means you can control 2 seperate circuits with a single action.

Let's say we want to use the switch to control a reverse light and reverse beeper. Here's how we would wire the switch:

1.) Connect the Power Source:
Connect a 12V power source from the vehicle's battery to pins 2 and 5 of the switch. These pins will supply power to both the reverse light and the reverse beeper circuits.

2.) Connect the Outputs:
Connect pin 3 to the relay for the reverse light.
Connect pin 6 to the relay for the reverse beeper.
These outputs will activate the respective relays when the switch is turned on.

That's it! Now when the switch is turned on, it will supply power to both the reverse light and the reverse beeper simultaneously. When the switch is turned off, power will be cut off to both circuits, ensuring the accessories deactivate together.

Remember, the wiring for a 4-pin rocker switch will vary depending on the application. Be sure to consult the switch's documentation or a wiring diagram before wiring the switch in your circuit.
