Electricians screwdrivers

The screwdriver is the most widespread handheld tool, commonly used by electricians, DIY enthusiasts, or professionals. Among the variations of screwdrivers, there is the electrician's screwdriver, also known as a tester screwdriver. Tester screwdrivers contain a lamp that lights up when the tool is in contact with an electric current ranging from 12 to 220 volts.

Generally equipped with a sheathed blade, the electrician's screwdriver is primarily used to detect the presence of voltage between 10 and 500 volts at a circuit point in any electrical distribution network thanks to a pilot lamp installed in the insulating handle that can withstand up to 1000 volts. This voltage detector effectively allows to check if cables and parts are truly de-energized before any manipulation for installation or repair work. To ensure the user's safety while providing a good grip, the handle of a tester screwdriver is always designed according to international safety standards. Some tester screwdrivers are equipped with a clip, which allows you to attach them to a pocket, for example. Caution is required, however, with this type of screwdriver, as it does not light up on a low voltage or neutral. That's why professionals today use electronic testers, also known as multimeters, devices that detect the presence of the electric field from a short distance.
