12v 2 Way Switch Wiring Diagram

Wiring a 12v 2 way switch can be overwhelming for those who are not familiar with electrical wiring. However, it is a simple process that can be easily mastered with the right information. In this article, we will discuss everything you need to know about wiring a 12v 2 way switch, including the necessary tools, materials, and step-by-step instructions.

What is a 12v 2 Way Switch?

A 12v 2 way switch is a type of electrical switch that allows you to control a circuit from two different locations. This means that you can turn the circuit on or off from either location, making it a convenient option for controlling lighting, fans, or other electrical devices in your vehicle or boat.

There are two types of 2 way switches: single pole and double pole. Single pole switches are more commonly used in homes, while double pole switches are used in vehicles and boats where a 12v power source is present.

Single Pole Vs. Double Pole Switches

Single pole switches are typically used to control one circuit or device. They have two terminals, one for the incoming power and one for the outgoing power. Double pole switches, on the other hand, have four terminals, two for the incoming power and two for the outgoing power.

Double pole switches are used in vehicles and boats because they can handle higher voltages and amperages than single pole switches. They are also more durable and can withstand the vibrations and shocks that come with driving or boating.

Tools and Materials

The following tools and materials are necessary for wiring a 12v 2 way switch:

Tools Materials
Screwdriver 12v two-way switch
Wire stripper 12v power source
Wire connector Electrical tape
Wire cutter Wires (black, red, and white)

Step-by-Step Instructions

Step 1: Turn off the Power

Before starting any electrical work, it’s important to turn off the power to the circuit you will be working on. In the case of a 12v circuit, disconnect the battery or turn off the power source.

Step 2: Connect the Wires

Next, strip the insulation off the ends of the wires that will be connected to the switch. The black wire is the power wire, the red wire is the load wire, and the white wire is the ground wire.

Connect the black wire to the common terminal of the switch and the red wire to either of the two remaining terminals. Connect the white wire to the ground terminal of the switch.

Step 3: Test the Circuit

After connecting the wires, turn on the power source and test the circuit to make sure it’s working properly. Flip the switch and check if the circuit turns on or off from both locations.

FAQ

What is the difference between a single pole and a double pole switch?

A single pole switch is used to control one circuit or device, while a double pole switch is used to control two circuits or devices. Double pole switches have four terminals, while single pole switches have two terminals.

Can I use a single pole switch instead of a double pole switch?

No, you cannot use a single pole switch instead of a double pole switch. Double pole switches are designed to handle higher voltages and amperages, and are necessary for controlling circuits in vehicles or boats.

What is the common terminal on a 2 way switch?

The common terminal on a 2 way switch is the terminal that receives the incoming power. It is typically labeled as “COM” or has a black screw.

What is the load wire on a 2 way switch?

The load wire on a 2 way switch is the wire that carries the power to the device or circuit that is being controlled. It is typically labeled as “L1” or has a red screw.

What is the ground wire on a 2 way switch?

The ground wire on a 2 way switch is the wire that provides a safe path for electrical currents to flow in case of a short circuit. It is typically labeled as “GR” or has a green screw.

Wiring a 12v 2 way switch is a straightforward process that can be done easily by following the steps outlined in this article. With the right tools and materials, you can control your vehicle or boat’s electrical devices conveniently from two different locations.
