A switch is a make - break device. Its function is a circuit is to make and break the current flow of the circuit that it is in. This action then starts and stops the load that is connected in the circuit.
a switch is used to isolate the a flow of current through a circuit , by breaking its connection, there is often a switch at the beginning of a circuit which would isolate the supply - voltage , from the load or " circuit " , in terms of higher - rated voltage circuits ( mains power) ; the switch performs a safety function where it provides a quick , safe and effective means of swathing off the circuit , providing a safety function - purpose , allowing the user to quickly remove power in the event of an emergency , for the switch to carry out its duty, it needs to have an air gap across its contacts contained within , rated so that at the designed/ rated voltage it maintains safety isolation / not allowing an electric arc / spark to jump across the gap .
When the switch is open, the circuit is not a complete circuit. Electricity needs a complete circuit of conductive material. The switch breaks the circuit causing the flow of electricity to be disrupted. When you close the switch, a full circuit is restored thus restoring the flow of electricity.
If the circuit is complete then it shouldn't matter where the switch is located. All a switch is specifically is a segment of the circuit that can be connected and disconected.
A relay will have a control circuit and a function circuitcould be the same feed line. One set of terminals (Hot and Load) can be activated at all times, but will not function until the control circuit is closed. The control circuit has a Hot and a Ground--when activated either by supply hot or ground by switch. The internal coil closes allowing the function circuit to operate. The purpose of this relay is to reduce the spike to the alternator. It takes less current (voltage) to close the coil on the relay than it would to operate the accessory that it controls

what does closed switch mean
what is the function of ic 4017 in clapswitch?
The function of a mechanical switch is to open or close a circuit by hand as opposed to an electronic switch which works electronically.
So that when the switch is in the open position the circuit is open and electricity cannot complete the circuit. When the switch is closed it completes the circuit and electricity flows completing the circuit and powering the device.
switching on the tourch for example is when as you switch it on it will move the switch connecting it to a circuit that lights up the bulb and when you switch the switch off the switch will move breaking the circuit
A switch simply opens a circuit, stopping the flow of electricity. For example: a simple circuit would be two wires from a battery, one of which goes to a switch, and the other goes to a light bulb. A third wire goes from the other side of the switch to the other conductor of the light bulb. With the switch closed the circuit is complete and the light goes on. Open the switch and the circuit is broken and the light goes off.
The purpose of a switch in an electric circuit is to control the flow of electricity by opening or closing the circuit. When the switch is closed, it allows electricity to flow through the circuit, completing the path for the current. When the switch is open, it breaks the circuit, stopping the flow of electricity. This on/off functionality of the switch helps to control the flow of electricity in the circuit.
TO open and close so that we can make it complete
Auxiliary switches are separate switches with circuit which helps for the function of commutation of main switches of a converter.

A soft iron core can function as a switch in an electromagnet system by being magnetized when a current is applied, allowing the electrical circuit to be completed and turning on the switch. When the current is turned off, the soft iron core loses its magnetization, breaking the circuit and turning off the switch.
A 4-wire switch functions in a circuit by allowing the user to control the flow of electricity through four different connections. The switch can be used to open or close the circuit, turning the power on or off to the connected devices.
