    摘要: A hand tool (10) that provides an alarm signal to a user as the tool approaches a live electrical wire is disclosed. The hand tool (10) comprises a tool head coupled to a handle. A non-contact voltage sensing circuit including an antenna is provided in the handle of the tool (10). As the tool (10) approaches a live electrical wire, the non-contact voltage sensing circuit detects the voltage, triggering an alarm circuit that provides a visual or audio signal to the user.

    摘要: A hand tool which provides an alarm signal to a user as the tool approaches a live electrical wire is disclosed. The hand tool comprises a tool head and coupled to a handle. A non-contact voltage sensing circuit is provided in the handle of the tool. As the tool approaches a live electrical wire, the non-contact voltage sensing circuit detects the voltage across the air gap between the tool head and the electrical wire, triggering an alarm circuit. The alarm circuit provides a visual or audio signal to the user.
