Construction of Electric Switch
The construction of electric switch consists of following components which works in its own way and these components are present internally or externally in it:
- Actuator or Toggle: This is the part of the switch that you physically operate to make or break the connection. It can be a lever, button, or rocker, depending on the switch type.
- Contacts: Contacts are conductive elements inside the electric switch which can make or break electrical connections. In an electrical switch, there are two contacts, one stationary and one movable. When the electric switch is in the “on” position, the movable contact touches the stationary contact, which allows the electric current to flow.
- Terminals: These are the points to which electrical wires are connected. In an SPST switch, there are two terminals, one for each contact.
- Housing: The switch components are enclosed in a housing made of insulating material to protect against electrical shock and environmental factors.
Electric Switch
An electric switch is an important component in an electrical circuit. An electric switch is a simple device that either breaks the circuit or completes it to stop or start the flow of current. An electric switch is an arrangement to switch the circuit ON and OFF as needed. It is also called a “Key” component in an electrical circuit. Basically, it is used to interrupt the general flow of electrons. In this article we will learn about Electric switches, the Working of electric switches, the construction of electric switches and different types of electric switches, and advantages and disadvantages, and their applications.
