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.
It is an insulator.

The opposite of a conductor (conducts electric flow) is a non-conductor, or something that opposes the flow, which would be an insulator.
No, a copper cooking pan is a conductor, not an insulator.
If an insulator with a lamp is connected in an electrical circuit and the switch is turned on, the lamp will not light up. Insulators do not allow the flow of electric current, so the circuit will not be completed, and no electricity will reach the lamp to cause it to light up.
The "hot" conductor of the lamp circuit.
A screw contact is typically made of metal, which is a conductor. This means it allows the flow of electric current through it.
wood is an insulator because charges stay on the point of contact.
