Definition Of Switches

SwitchA Switches is an electrical component or  An electrical switch that can “make” or “break” an electrical circuit interrupting the current or diverting it from one conductor to another. The mechanism of a switch it removes or restores the conducting path in a circuit when it is operated by any one. It may be operated manually. That is a light switch or a PC operating switch, also alarm switch. In any case, the final output of any switch will be (at least) a pair of wire-connection terminals that will either be connected together by the switch’s internal contact mechanism (“closed”), or not connected together (“open”).

Any switch designed to be operated by a person is generally called a hand switch, and they are manufactured in several varieties.

They are:SPST

(1) Switch (SPST)-: A Single pole single throw Switch, the two terminals are either connected  together or dis-connected from each other. When two conductor connected with  each other then switch is closed and  its given a output, obviously when two conductor  dis-connected from each other then switch is open so in this condition switch can’t  work.

SPDT(2) Switch (SPDT)-: A Single pole  double throw Switch of a simple type of changeover electrical switch. its has three terminal. hence one terminal fixed and another two terminal connected to a main line that means (phase and neutral)  which can control two separate circuits, but are always switched together by a single actuator.

DPDT(3) Switch (DPDT)-: When we adding another pole to the SPDT then  creates a Double Pole Double Throw (DPDT) switch. It has two separate common terminals and each of those is connected to one or the other of the other two terminals on the same side of the switch. Two SPDT switches, which can control two separate circuits, but are always switched together by a single actuator.  Six terminals should have in  a DPDT Switch.

(4) Bed Switch-: These type of switch is basically used for  ON or OFF the light from any place, of other than from near the board. While going to sleep or getting up then you can easily control light by these switch,it is also known Pendant type switch. It is connected in series with all of the two flexible wires.
