What are the Types of Switches? (Electrical & Mechanical Switches)

In this video, I will explain the types and working principles of mechanical switches used in electrical and electronic circuits. A Switch is a simple device that is used to break a circuit and disturb the flow of electrons.
A switch can be either closed or open. A closed switch is 'On' and will activate the circuit whereas an open switch is 'Off' and will interrupt or break the circuit.

Switches can be either Mechanical or Electronic. A Mechanical Switch is activated with a physical action; pressing, moving or touching its contacts. An Electronic Switch is activated differently and does not need physical contact; instead it is activated by semiconductors such as transistors. This lesson will focus on Mechanical Style Switches.

This section we will look at the most common types of Mechanical Switches. These are Toggle Switches, Push Button Switches, Rocker Switches, Rotary Switches, Slide Switches and Microswitches to name a few.
