2 Pins Rocker switch wiring diagram

This is the most basic type of switch – the On/Off rocker switch,

It has just 2 pins:

Myoffroad rocker switches can be hooked up to any 12volt source, everything else is pretty self-explanatory, just follow the rocker switch wiring diagram and you can’t go wrong.

For the LED rocker switch, pay careful attention to the position of your ground, power and acc pins, follow the diagram below, and you should have no problems wiring a LED rocker switch:

Mystery offroad 3 pins rocker switch

Myoffroad rocker switches are available in:

Plain/Regular (No LED. Does not light up)
Blue (LED lights up when switch is on)

Green (LED lights up when switch is on)
White (LED lights up when switch is on)
Amber (LED lights up when switch is on)
On / Off / On (A 3 position switch. No LED)

This switch also has a built-in LED that lights up when it’s in the on position, so if you’ve purchased one of these, below is a wiring diagram showing how you would go about wiring this particular light switch, remember to pay careful attention to the markings on the pins:

Rocker Switch Internal Construction Diagram

We will now go over the wiring diagram, so that you can know how rocker switches are internally constructed.

This will help you visualize how rocker switches work, so that you can know how to connect them.

Below is the internal construction of a SPST rocker switch:

Based on this diagram above of the internal construction of a rocker switch, you can see that it can be in one of two states. It can be turned to one side or turned to the other. This allows you to flip a device on or off. The metal bearing snaps down the switch so that it makes contact with one of two sides, depending on which side the switch is flipped to.

SPST Rocker Switch Wiring Diagram

Now that you have an idea how rocker switches are constructed internally, let’s go over the wiring diagram, so that you will now how to connect a rocker switch to a circuit.

As shown below, rocker switches have 3 electrical connections.

The diagram below represents the schematic diagram for a SPST rocker switch:

Pin 1 is where the rocker switch receives the input power. Pin 2 is where the accessory that the switch is going to turn on is connected. Pin 3 is where the switch is either connected to ground or left open.

Below is a pictorial representation of the schematic diagram:

This translates into the following model in a real life rocker switch:

Below are the 3 pins that form electrical connection with a circuit, each described with their function in the circuit:

Electrical Connections	Function
Power	This is the pin where the rocker switch receives its voltage.
Accessories	This is the pin that connects to the load of the circuit, whatever the rocker switch turns on when it’s switched on. Ex: lights, motor, etc.
Ground	This is the pin that connects to the ground of the circuit.

Now these are the 3 pins which establish electrical connection to the circuit we are wiring the rocket switch to.

There is the pin which receives the power. There is the pin which connects to the load we are going to power. And there is the pin which connects to the ground of the circuit.
