Detailed Solution

The above statement is True.
Air is the insulator a switch uses to cut off the current in a circuit.
As opposed to insulators, which prevent current from passing through them, conductors allow current to flow through them. An object used to complete or interrupt a circuit is a switch. Air is the substance that the switch uses to interrupt the circuit.
Air is the main insulator that breaks the circuit, although other insulators also have an impact. Air acts as the principal insulator in the simplest type of switch, the knife switch. However, the input and output terminals are also isolated from one another by the switch's body (made of ceramic, plastic, etc).
