Abstract
A trigger assembly, for use with a power tool having an electric motor, includes a trigger, a conductor coupled for movement with the trigger, and a printed circuit board. The printed circuit board has an inductive sensor thereon responsive to relative movement between the conductor and the inductive sensor caused by movement of the trigger. An output of the inductive sensor is used to activate the electric motor.
Claims25
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;
- 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.
A power tool comprising:
- an electric motor;
- a controller in electrical communication with the motor to activate and deactivate the motor;
- 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 detected by the controller, which in response activates or deactivates the electric motor.
A method of operating a power tool, the method comprising:
- pressing a trigger in a first direction;
- moving a conductor over an inductive sensor;
- outputting a signal from the inductive sensor;
- and
- activating an electric motor based on the signal.
