Toggle switches are electronic components that control a circuit's state. An on/off switch is operated by moving the lever or button between two positions, typically "on" and "off." When the toggle switch is in the "on" position, the circuit is completed, and electricity can flow through it, enabling the connected device or system to function. Conversely, the "off" position of the toggle switch breaks the circuit, interrupting the flow of electricity and turning the device off. Toggle switches can be categorized into different types, such as waterproof toggle switches, toggle light switches, brass toggle switches, and mini toggle switches. They can also be classified based on their function, including ON-OFF momentary toggle switches and ON-OFF-ON toggle switches.
