A rocker switch is a type of electrical switch that operates by rocking or tilting a lever back and forth. It is commonly used in various devices and appliances, such as light fixtures, power strips, and home electronics. The design allows for easy operation, often with a simple push of a finger. These switches typically have two positions: on and off. When the switch is pressed down on one side, it completes the electrical circuit, allowing power to flow. When pressed on the opposite side, it breaks the circuit, turning the device off. Rocker switches are popular for their user-friendly design and reliability.
