Mains Testers
The Faithfull Mains-Tester Small Screwdriver is a handy tool made from virtually unbreakable and shatterproof ABS.
To test the circuit place the screwdriver end on the electric contact and press your thumb against the metal contact next to the neon viewing window. The handle, pocket clip and blade are insulated for maximum safety. If the circuit is live the bulb will light.
