👉According to the operation required they are classified as:
→One-way switches
→ Two-way switches
→Two-way centre-off switches
→Double pole main switches
→Push button switch
→Table lamp swich
✏️ONE WAY SWITCH
👉This type of switch contains two terminals.
👉The switch is always connected in series with point(lamp,fan to be controlled).
👉The switches usually are for use upto 250 volts and 5 or 6A.
✏️TWO WAY SWITCH
👉The switch of this type consists of four terminals,two of them is short circuited inside the switch.
👉The switch of this type is usually used in stair case wiring or circuit where one point is to be controlled from two different places.
✏️TWO WAY CENTRE OFF SWITCHES
👉This switch is same as two way switch but having three operations.
👉In the centre it becomes off.
👉Such switches are used when two lamps are operated alternatively.
✏️DOUBLE POLE MAIN SWITCHES
👉This is the combination of two one way switches.
👉It can be operated simultaneously as the ON-OFF terminals of both the switches are connected together by the handle made of bakelite.
👉Such switches are used as interlinked switches when the load current is less than 5 amperes and supply voltage is under 250 volts.
✏️PUSH BUTTON SWITCH
👉Such switches are used for controlling bells.
👉When the knob is pressed,the circuit is completed and bell rings and as soon as the knob is left,the circuit becomes open.
✏️TABLE LAMP SWITCHES
👉This is a small ON-OFF switch which is commonly used in table lamps.
✏️SURFACE SWITCHES (TUMBLER SWITCHES)
👉Tumbler switches are those which are fixed on mounting blocks directly fixed on the surface of the wall.
👉Such switches project out of the surface of the wall and are in common use
👉They are available in round and oblong base.
✏️FLUSH TYPE SWITCHES
👉Flush switches,as obvious from its name are fixed flush with the wall and do not project out.
👉These type of switch is used where high quality performance and appearance are required.
