The present invention is an efficient high voltage sensing mechanism that operates only when an individual needs to test the voltage across a wire. The present invention attaches around a tested wire using a jaw and a hook. The hook is tensioned using an expansion spring. The operator propels the hook outwards from the jaw, around the tested wire; thereafter, the expansion spring retracts to latch onto the tested wire against the jaw. An on-off switch is integrated into the mechanical hook device. As the hook is propelled outwards, the on-off switch moves into the on position, which powers the electrical processing and voltage analysis equipment. Once the hook is returned to the initial position, the on-off switch moves to the off position. This arrangement allows the present invention to remain unpowered for any instance a wire is not being tested. The present invention detects voltage through capacitive coupling.
