A rocker switch is an electrical component that is commonly found in various devices and applications. This type of switch is designed to control the flow of current from one circuit to another. A 3 position rocker switch, as its name implies, has three different positions that allow you to control the flow of current in different ways. In this article, we will discuss how to wire a 3 position rocker switch and provide you with a wiring diagram to help you get started.
What is a 3 Position Rocker Switch?
A 3 position rocker switch is a type of switch that has three different positions: ON, OFF, and MOMENTARY. The ON position allows the flow of current through the switch, while the OFF position interrupts the flow of current. The MOMENTARY position allows the flow of current for as long as the switch is pressed or held down.
These switches come in a variety of shapes and sizes, and can be used in various applications. They are commonly found in appliances, automotive, marine, and other electronic devices, and are used to control different functions or features.
How to Wire a 3 Position Rocker Switch?
Wiring a 3 position rocker switch may seem daunting, but it is actually a simple process that can be done by anyone with basic electrical knowledge. Before you begin, you will need a few tools and materials:
- 3 position rocker switch
- Wire cutters/strippers
- Soldering iron/solder
- Wiring diagram
Step 1: Determine the Pinouts
The first step in wiring a 3 position rocker switch is to determine the pinouts of the switch. This will depend on the specific switch that you are using, and you can find this information in the datasheet or user manual that comes with the switch.
Typically, a 3 position rocker switch will have six pins, arranged in a double-pole, double-throw (DPDT) configuration. This means that there are two sets of pins, each with a common pin and two other pins (A and B).
The pinouts for a DPDT 3 position rocker switch are as follows:
| Pin 1 | Common (C) |
| Pin 2 | A |
| Pin 3 | B |
| Pin 4 | Common (C) |
| Pin 5 | A |
| Pin 6 | B |
Step 2: Prepare the Wires
Next, you will need to prepare the wires that will connect to the switch. You will need three wires: one for the power source (positive), one for the load (the device or appliance that the switch will control), and one for the ground (negative).
Using the wire cutters/strippers, strip the ends of the wires and tin them with solder. This will make it easier to connect them to the switch and ensure a good connection.
Step 3: Connect the Wires to the Switch
Using the wiring diagram as a guide, connect the wires to the switch. The power source should connect to the common (C) pin on one side of the switch, and the load should connect to the A or B pin on the other side of the switch, depending on which position you want to use.
The ground wire should be connected to the common (C) pin on the opposite side of the switch from the power source. This will complete the circuit and allow the switch to function properly.
