When it comes to controlling electrical devices in your vehicle, an illuminated rocker switch is often the go-to choice. It allows you to easily see if the device is on or off, even in dark environments. In this article, we will discuss the wiring diagram for a 12 volt illuminated rocker switch and provide useful information to help you successfully wire the switch for your specific needs.
What is a 12 Volt Illuminated Rocker Switch?
A 12 volt illuminated rocker switch is a switch that has an additional light feature, which illuminates the switch when it is turned on. The switch is commonly used in vehicles to control a variety of electrical devices such as lights, fans, and radios. The switch is easy to use and provides a clear indication of the status of the device it controls.
How Does an Illuminated Rocker Switch Work?
The illuminated rocker switch has three pins which need to be connected to the electrical circuit for it to work. The first pin is the ground, and it is usually connected to the vehicle’s negative battery terminal or a ground wire in the electrical system. The second pin is the power supply, which is connected to a 12-volt power source. The third pin is the load, which is connected to the device you want to control.
Why Use an Illuminated Rocker Switch?
Using an illuminated rocker switch provides an easy way to see when the device is on or off, without having to guess or use trial and error. It can help prevent accidental device activations, which can drain your vehicle’s battery or cause other issues.
Wiring Diagram for a 12 Volt Illuminated Rocker Switch
Before we dive into the wiring diagram, it is important to understand the different types of illuminated rocker switches that are available:
Type | Description |
---|---|
SPST | Single Pole Single Throw – one switch, one circuit |
SPDT | Single Pole Double Throw – one switch, two circuits |
DPDT | Double Pole Double Throw – two switches, two circuits |
The wiring diagram for a 12 volt illuminated rocker switch will vary depending on the type of switch you are using. However, the basic wiring principles are the same:
Step 1: Determine the Type of Switch
Before you start wiring your illuminated rocker switch, you need to determine the type of switch that you are using. This will help you identify the pins and how they need to be wired.
Step 2: Connect the Ground Wire
The ground wire is usually connected to the switch’s first pin. This will allow the switch to be grounded and provide power to the light when the switch is turned on. If you are unsure which pin is the ground, refer to the manufacturer’s instructions or use a multimeter to test the pins.
Step 3: Connect the Power Supply Wire
The power supply wire is connected to the switch’s second pin. This will provide power to the switch and the device that it controls. Make sure that the power supply wire is connected to a 12 volt power source.
Step 4: Connect the Load Wire
The load wire is connected to the switch’s third pin. This will allow the switch to control the device that you want to turn on or off. Make sure that the load wire is connected to the correct device and is properly grounded.
Step 5: Test the Switch
Once you have wired the illuminated rocker switch, it is important to test it to make sure that it is working correctly. Turn the switch on and off to ensure that it is responding correctly and that the light is illuminating as expected.
