Key switches are an important component of many different types of electrical devices. They allow you to turn a device on and off using a key, which can be a useful security feature. One common type of key switch is the 4 wire key switch. In this article, we’ll take a closer look at the 4 wire key switch wiring diagram.
What is a 4 wire key switch?
A 4 wire key switch is a type of key switch that has four wiring connections. The four wires are typically labeled as follows:
- Ground
- Battery
- Accessory
- Ignition
The ground wire is used to connect the switch to the ground or negative terminal of the device. The battery wire is used to connect the switch to the positive terminal of the battery. The accessory wire is used to control any accessories that might be connected to the device (e.g. lights, radio, etc.). Finally, the ignition wire is used to control the ignition system of the device (e.g. spark plug, fuel pump, etc.).
How to wire a 4 wire key switch?
Wiring a 4 wire key switch is fairly straightforward. Here are the steps:
- Identify the four wires on the key switch and their corresponding labels (ground, battery, accessory, and ignition).
- Connect the ground wire to the ground or negative terminal of the device.
- Connect the battery wire to the positive terminal of the battery.
- Connect the accessory wire to any accessories that might be connected to the device (e.g. lights, radio, etc.).
- Connect the ignition wire to the ignition system of the device (e.g. spark plug, fuel pump, etc.).
- Test the key switch to make sure it is working properly.
It’s important to note that the exact wiring diagram for a 4 wire key switch may vary depending on the device and manufacturer. Always refer to the device’s user manual or wiring diagram for specific instructions.
