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
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.
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.
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.
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.
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.
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.
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.
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.
