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.
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
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
