4 Terminal Rocker Switch Wiring Diagram

A rocker switch is a popular type of switch that is commonly used in various electrical applications. It is easy to use and provides a reliable on and off operation. In this article, we will discuss the 4 terminal rocker switch wiring diagram, its components, installation, and frequently asked questions.

Components of a 4 Terminal Rocker Switch

A 4 terminal rocker switch has four connectors that are used to connect it to a power source, load, and control panel. The four terminals are:

  • Positive or Input Terminal
  • Negative or Ground Terminal
  • Load Terminal 1
  • Load Terminal 2

Most rocker switches have a built-in light that illuminates when the switch is in the on position. This light is powered by a separate terminal that is connected to a power source.

Positive or Input Terminal

The positive or input terminal is used to connect the switch to a power source. It usually has a 12-volt DC or AC rating. This terminal is connected to the power source using a wire or cable.

Negative or Ground Terminal

The negative or ground terminal is used to connect the switch to the ground or negative battery terminal. It is used to complete the circuit and provides a safe path for electrical current to flow in case of a short circuit.

Load Terminal 1 and Load Terminal 2

The load terminals are used to connect the switch to the load or device that needs to be switched on or off. The terminals are connected to the load using wires or cables.

Light Terminal

The light terminal is used to connect the switch light to a power source. It is usually connected to the positive terminal and provides power to the light when the switch is in the on position.
