Mains voltage testers in screwdriver form

A voltage tester in screwdriver form is the quickest check on a socket outlet, a switch or a light fitting: touch the tip to the conductor, close the circuit through the top cap and the neon or LED indicator answers at once. Blades run from around 3 mm for terminal screws up to wider slotted tips for consumer unit work, and a pocket clip keeps the tester where a fault call needs it.

Single-pole phase testers identify the live conductor on mains circuits rated to 250V. They are made for orientation, not for proving dead, and a two-pole instrument is the right tool where a circuit has to be confirmed isolated, because a single-pole tip can be fooled by induced voltage on long or parallel runs.

Look at blade insulation, overall length and how readable the indicator stays in daylight. The wider screwdrivers range and the matching nut driver sizes cover the rest of the same bench and panel work.
