A toggle switch is a type of electrical switch that is operated by moving a lever or handle back and forth to open or close a circuit. Toggle switches are commonly used in various electronic devices and equipment to control electrical power or signal flow. They are reliable, easy to use, and versatile, making them ideal for a wide range of applications.
Working Principle of a Toggle Switch
The working of a toggle switch is simple and involves mechanical movement:
- The lever or handle of the switch is moved manually to change its position.
- Depending on the switch type (e.g., SPST, SPDT), the movement of the lever either connects or disconnects the electrical circuit.
- Internally, the movement aligns contacts to allow or interrupt the flow of current, completing or breaking the circuit.
Types of Toggle Switches
Type | Description |
---|---|
SPST | Single Pole, Single Throw: A simple ON/OFF switch controlling a single circuit. |
SPDT | Single Pole, Double Throw: Toggles one input between two output circuits. |
DPST | Double Pole, Single Throw: Controls two circuits simultaneously with one ON/OFF action. |
DPDT | Double Pole, Double Throw: Toggles between two output circuits for two inputs. |
