A toggle switch is a type of electrical switch that allows users to turn a device on or off by flipping a lever or handle. It typically has two positions: one for the "on" state and another for the "off" state. Toggle switches are commonly used in various applications, including household appliances, lighting systems, and machinery, providing a simple and reliable way to control electrical circuits. These switches come in different sizes and styles, including single-pole and double-pole configurations, depending on the number of circuits they control. Toggle switches are often mounted on panels or walls and can be made from materials like plastic or metal, ensuring durability and ease of use in everyday settings.
