The insulator of a lamp is the glass because it helps protect people from the heat.
Please re define "If an insulator with a lamp"
yes you can test it under a lamp and see the temp. for the foam and paper and if one has the lowest than that's the better insulator!good luck!
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.
