An electric switch is a device used to control the flow of electricity in a circuit. It allows users to turn electrical devices on or off by connecting or disconnecting the electrical path. Electric switches are widely used in homes, industries, vehicles, and electronic devices for safety and convenience.

Types of Electric Switches
1. Mechanical Switches
These require physical interaction to operate. Examples include:

Toggle Switch – Flips up or down to open/close a circuit.

Push Button Switch – Requires pressing to activate (e.g., doorbells).

Rotary Switch – Turns in steps to select different electrical connections.

Slide Switch – Moves horizontally to connect or disconnect a circuit.

2. Electronic Switches
These rely on semiconductors and are used in modern applications. Examples include:

Transistor Switch – Uses electronic signals to control the circuit.

Solid-State Switch – Operates without moving parts, improving durability.

Membrane Switch – Found in touch-sensitive appliances and keypads.

3. Specialized Switches
Designed for specific applications, such as:

Limit Switch – Activates when an object reaches a certain position (used in industrial machines).
