What Are Switches?

Switches are electronic components designed to control the flow of electrical current in a circuit. They can be manually operated or controlled electronically. The primary function of a switch is to either connect or disconnect a circuit, thereby allowing or preventing the flow of current.

Functions of Switches:

Control: Switches are used to turn devices on or off.

Protection: They can be used to protect circuits from overcurrent or short circuits.

Selection: Switches allow for the selection of different circuits or functions.

Isolation: Switches can isolate different parts of a circuit.

Types of Switches:

Mechanical switches: Operated manually by a physical action, such as flipping a lever or pressing a button.

Toggle switches: Commonly used in appliances and electronics.

Push-button switches: Used for momentary actions or maintaining a state.

Rotary switches: Used for selecting from multiple positions.

Electrical switches: Operated by electrical signals.

Relays: Electromagnetic switches used for high-current or high-voltage applications.
