1. A trigger assembly for use with a power tool having an electric motor, the trigger assembly comprising:
a trigger;
a conductor coupled for movement with the trigger; and
a printed circuit board having an inductive sensor thereon responsive to relative movement between the conductor and the inductive sensor caused by movement of the trigger,
wherein an output of the inductive sensor is used to activate the electric motor,
wherein the conductor moves between a first position and a second position, and
wherein the first position is outside the detection area of the inductive sensor and the second position is within the detection area of the inductive sensor.
