Types Of Switches

In this article we learn about how many types of switches . we will also know about types and their application of switches.

Types of switches

types of switches, main types of switches, switches type
In any electrical circuit various types of switchs are used to star or stop the flow of current. Depending upon work,construction and current rating, types of switches are given below.
Based on working methodology, various types of switches are given

1. Single Pole One Way Switch

This is the simplest form of switch. It is used to ON/OF any electrical appliance.

Single Pole Two Way switch

It has one pole and two paths, it is used to ON/OFF one out of two lamps or it is used in staircase circuits which is controlled by two locations.
Intermediate Switch 
It is a four terminal device. The intermediate connections can be horizontal to principal axis or cross form. It is used to control electrical appliance from three or more places.

2. Push Button Switch

Push button switch consists of a spring control mechanism. On pressing the switch, the current starts flowing in the circuit until thee switch remains pressed while on releasing the switch, the flow of current stops. Such switches are used in electric bell, buzzer,matches,etc. push button switches are of two types push to ON switch and push to OFF switch.

3. Ceiling Switch

It is a push button type of switch. This types of swiches is employed in wiring inside a structure, operated by a pulling motion on a chain or cord,mounted to the ceiling .
On pushing/pulling one time current starts to flow in the circuit. The circuit is ON pulling/pushing next time current stops to flow in the circuit that is off.  It is also called as bed lamps, night lamps, table lamps, etc.

4. Double Pole Iron Clad or DPIC switch

It works as a main type of switch. it used  as main switch for single phase AC/DC. A fuse is connected in series with each line. It is used for controlling single phase 2-wire circuits. The switch switches ON/OF the phase line and neutral line simultaneously.

5. Three Pole Iron Clad or TPIC Switch

It works as a main switch for 3-phase AC line. It is used for controlling a 3-phase power with 4-wire system. A fuse and a neutral link is connected in series with each line. The switch switches ON/OFF all the three phase lines simultaneously.

6. Knife Switch

It is an uncovered switch can handle large amount of current. They are used in substations or distribution stations. They are constructed for 30A to 1000A current. These switches can be so single throw, double throw and 3-phases types.

7. Tumbler types of switches

These types of switches are surface mounted switches, they can be of one pole one way and one pole two way switch types. These switches are rarely used.
Flush type of switch
These types of switches are fitted inside the surface of switch boards and only the lever of switch is outside the boards and only the lever of switch is outside the board. They can be of one pole one way and one pole two way switch types. These types of switches are used now-a-days.

8. Toggle Switch

types of switches, main types of switches, switches type
These types of switches are fitted inside the surface of switch board and only the metallic lever and a brass ring is visible. They can be of one pole one way, one pole two way and intermediate seitch types. They are used in electrical and electronic appliances.

9. Slide Switch

These types of switches are fitted inside the surface of switch board and only the lever is visible. They can be of one way; one pole two ways and multiple poles multiple way switch type.

Hence it is main types of switches if you will find any incorrect above article please comment below in comment box.
