Abstract:
A power tool includes a sensing circuit mounted on a printed circuit card is electrically connected to a switching power supply that supplies electrical power to the sensing circuit. The sensing circuit is not connected to earth ground to enable detection of an operator approaching a moving implement without the operator necessarily being electrically connected to earth ground.
