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 applications, including household appliances, automotive controls, and industrial equipment. The design allows for easy operation, often with a simple push to turn the device on or off. Rocker switches come in different styles and sizes, often featuring a visual indicator to show whether the device is on or off. They can be found in both single-pole and double-pole configurations, making them versatile for different electrical circuits. Common examples include light switches and power strips.
