A toggle switch is a simple electrical device used to control the flow of electricity in a circuit. It typically has a lever or handle that can be flipped up or down to turn a device on or off. Toggle switches are commonly found in household appliances, light fixtures, and various electronic devices. These switches come in different styles and sizes, including single-pole and double-pole configurations. They are designed for easy operation and can be mounted on panels or walls. Toggle switches are widely used in both residential and industrial settings for their reliability and straightforward functionality.
