The "contact" ... that is, the point where one side of the power circuit is connected ...

must be a conductor. When the switch is 'open', then one contact is physically separated

from the other one, and no current flows between them. But the contacts themselves are

still conductors.

A switch is a device that has both conductor and insulator,

off- insulator, then it resists the flow of electricity

on- conductor, then it allows charges to flow readily

Yes switch is a conductor. When switch on you actually close the circuit by inserting the conductor in switch in the broken part and hence joining the circuit.

must be a conductor. Otherwise the lamp doesn't behave like a lamp.
