Question

Draw the diagram of a dual control switch when the appliance is switched ‘ON’.

Answer 1

Hint: You can start by describing the concept of current briefly. Then define the concept behind the switches. Then move on to describing the dual control switch with examples of situations in which it is used, also draw the circuit diagram of dual control switch.

Complete step-by-step answer:
Current is essentially the flow of electrons in a circuit. The current can only flow through the circuit when the circuit is closed. It means there are no breaks in the circuit in between the high and low potential points.
Switches are a very important electrical device. Switches mostly contain one or more sets of movable circuit parts. The parts of the switch can be in either the ‘ON’ state or the ‘OFF’ state.
Dual control switch – This is a unique type of switch. This switch is used in situations where we want to have two control points for a circuit. For example – the stitches used on staircases, you may have seen it in your own house. There are two control points in this system, one of the control switches is present at the bottom of the staircase and the second at the top of the staircase. These switches are also used in rooms with two entrances.
The circuit diagram of the ‘ON’ of the dual control switch is given below.

As you can see either of the two switches can be used to switch ‘ON’ and ‘OFF’ the circuit.


Note: Switches are very important, they are used in our homes to control lights and machines. They are also widely used in production plants. Switches are important, because without switches we would have to keep our machines in ‘on’ state or use very dangerous open connections of wire that could lead to accidents.
