Electrical Screwdrivers
(2 products)Electrical screwdrivers are used to test circuits for an electrical current. Shaped like a regular screwdriver, the tip of the blade can be used to test bulbs and fuses or can be touched against a wire to see if there is an active current. A light will come on in the handle if a current is present. Electric tester screwdrivers usually feature a carbon steel blade and a plastic handle.
