    Rocker Switches

    A rocker switch is a type of electrical switch that consists of a lever or rocker that can be toggled between two positions: "on" and "off." They are sometimes referred to as a “on off switch”. You can learn more on how rocker switches work in our comprehensive Rocker Switch Guide.

    Here's some useful information on how to use rocker switches:

    • Function: Rocker switches are primarily used to control the flow of electric current to devices or circuits. They act as a bridge between the power source and the load (device) you want to control.

    • On and Off Positions: The rocker switch has two stable positions: "on" and "off", hence the name “on off switch”. In the "off" position, the switch interrupts the electrical circuit, preventing the current from flowing to the load. When you toggle it to the "on" position, the switch closes the circuit, allowing the current to reach the load.

    • Wiring: To use a rocker switch, you need to connect the switch terminals to the relevant wires. Typically, a rocker switch has three terminals: a common terminal (also called the "COM"), a normally open terminal ("NO"), and a normally closed terminal ("NC"). The common terminal is where you connect the power source or the live wire. The NO and NC terminals are for connecting the load or to the device you want to control.

    • Wiring Configurations: The wiring configuration will depend on your specific application and the desired behaviour of the switch. For instance:

      • If you want the load to be energized when the switch is in the "on" position, you would connect the live wire to the COM terminal and the load wire to the NO terminal.

      • If you want the load to be energized when the switch is in the "off" position, you would connect the live wire to the COM terminal and the load wire to the NC terminal.

    • Installation: Rocker switches are typically mounted onto a panel or a switch box using screws or clips. Make sure to follow the manufacturer's instructions for proper installation.

    • Applications: Rocker switches are widely used in various devices and systems, including household appliances, automotive applications, industrial machinery, and electronic equipment. They provide a convenient and straightforward way to control the power supply to different components.

    • Considerations: When choosing a rocker switch, consider factors such as the voltage and current rating, the switch's durability, and the environmental conditions in which it will be used.
