Types of Electrical Switches
Types of Electrical Switches
1. Single Pole One Way Switch
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
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 .
4. Double Pole Iron Clad or DPIC switch
It works as a main type of electrical switchs. 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
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 electrical 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
8. Toggle Switch
These types of electrical 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 switch types. They are used in electrical and electronic appliances.
9. Slide Switch
These types of electrical 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.
