Dangerous Device - Neon Mains Testing Screwdriver
How not to test for mains voltage, and why you should never use one of these neon screwdriver testing efforts for anything.
These devices are unreliable, can indicate power when there is none, and in certain circumstances not illuminate at all, even though 240V or more is present.
The neon indicator is difficult to see in bright light such as outside.
The entire safety of the device depends on a small resistor inside, which if failed will result in the full mains voltage appearing on the end cap where you place your finger.
This example has a large hole in the end cap, so that water, dirt and dust can easily enter and bridge across the resistor.
They are also useless as screwdrivers, since the blade is made from a very soft metal, the handle is thin plastic, and they easily break.
