The switch is a simple device used to either break the electric circuit or complete it.
The most common form of the electric power switch is a basic manual electromechanical unit. A switch is said to be in ON position when it makes or completes the circuit and allows the current to pass through. Similarly, a switch is in an OFF position when it breaks the circuit and does not allow the current to pass through. The most common form of the electric power switch is a basic manual electromechanical unit.
Categories of switches
- Single Pole: It controls just one circuit.
- Double Pole: Double Pole electric switches control to separate circuits.
- Three-Way: Using three-way switches, light can be control from two different locations.
- Four Way: A four-way switch has four terminals
- Multi-location switch: It is the interconnection of two or more electrical switches used to control an electrical load from multiple locations.
- Dimmer switch: It allows you to turn the light in several subtle shades.
Importance of electric switches
- Electric switches are significant because all the equipment we are using is useless without a switch.
- It is used to connect and break the flow of connectivity.
- They are used to perform all logical functions.
