●The one contact neon lamp voltage tester usually have the form of a screwdriver, it’s a simple piece of electronic test equipment used to determine the presence or absence of an electric voltage.

●Screwdriver test pen is a low-cost type of test lamp, let the tip of the tester contacts one side of the circuit under test, and rely on stray capacitance and current passing through the user’s body to complete the circuit. Because a neon lamp takes very little current to light, so we can use the user’s body capacitance to earth ground to complete the circuit.

●Shanguang produce voltage tester pen out of several materials with different appearance design according to global customer requirements for more than 29 years.

●A resistant plastic is used for the core which ensures that the blade is held securely even under high strain.

●We use the Wire-electrode cutting machine to produce the blade, This technique only our factory have in voltage tester industry in China. this technology to increase the hardness of a blade, which provides high frictional resistance and allows the application of high forces.
