Switch handles are a type of hardware used to control the flow of electricity. They are typically found in electrical boxes and are used to turn power on and off. Switch handles come in a variety of shapes and sizes and can be made from different materials such as plastic, metal, or wood. The term 'switch handles' is often used interchangeably with 'knobs' or 'levers'. Renaming switch handles is a job that involves replacing the existing handle with a new one, usually of the same size and shape.
