What is an Electrical Switch?
An electrical switch is a electrical device that regulates the flow of electrical power in a circuit by opening (or) closing it.
It’s essentially a binary device that may be turned on (closed) (or) off (open), allowing (or) preventing current passage.
Switches are essential components of electrical systems, allowing us to turn on and off equipment and govern power distribution.
Types of Electrical Switches
There are different types of electrical switches based on their application of use:
1). Limit Switch
2). Tactile Switch
3). Slide Switch
4). Rotary Switch
5). Emergency Switch
6). Push Button Switch
7). Selector Switch
8). SPDT Switch (Single Pole Double Throw)
9). DIP Switches
10). Timer Switch
11). Pressure Switch
1). Limit Switch
Used to determine the existence or absence of a physical object in a given region. Commonly utilized in production lines to automatically stop at a predetermined point.
2). Tactile Switch
A little switch in electronic circuits that can be pressed with your finger & produces a gentle clicking sound. This is common in control panels & small equipment.
3). Slide Switch
Operates by sliding a little lever to toggle between ON and OFF. Frequent in portable electronic appliances.
4). Rotary Switch
A circular switch that can be turned to select a specific position from among several options. Utilized in control panels (or) for selecting several speeds.
5). Emergency Switch
The large red emergency button was meant to immediately turn off power in dangerous conditions. Extremely vital in manufacturing and workplaces.
6). Push Button Switch
A temporary push button that returns to its original position when pressed. Used to start and stop machines, as well as in signaling systems.
7). Selector Switch
Used to select a specific mode; usually has multiple positions, such as manual/automatic (or) start/stop/reverse.
8). SPDT Switch (Single Pole Double Throw)
A switch that toggles between two electrical lines. Prominent in manual changeover circuits.
9). DIP Switches
A collection of small switches utilized to configure settings on electrical equipment (such as a printer or control board).
10). Timer Switch
Controls whether a circuit turns on or off after a set time. Used for lighting and time-based machine control.
11). Pressure Switch
When a predetermined pressure is attained, an electrical circuit is activated or deactivated. Utilized in air & water systems (such as compressors).
