Abstract
A power tool includes a tool body having an output member that drives an accessory. An end effector is coupled for rotation with the output member. A light source is disposed on the end effector. A primary coil assembly is configured on the tool body and mounted concentric to the output member. The primary coil assembly includes a primary coil that is electrically connected to a power source of the power tool. A secondary coil assembly is configured on the end effector and mounted concentric to the output member. The secondary coil assembly includes a secondary coil that is electrically connected to the light source. Current flowing through the primary coil creates a magnetic field that causes current to flow through the secondary winding and power the light source.
