Abstract

A power tool includes a working element, a motor, a motor actuator, a housing, a light emitting element, a locking element, and a switch element positioned between the housing and the locking element. The housing supports the motor, the motor actuator, and the light emitting element and movably supports the locking element. The light emitting element illuminates a work area around the working element, and the motor drives the working element when actuated by the motor actuator. The locking element enables operation of the motor actuator when in an unlocked position and prevents operation of the motor actuator when in a locked position. When in the unlocked position, the locking element operates the switch element to activate the light emitting element.

First claim

What is claimed is:

1. A power tool, comprising:
a working element;
a motor drivingly coupled to the working element;
a motor actuator configured to operate the motor;
a housing configured to support the motor and motor actuator;
a light emitting element supported by the housing and configured to illuminate a work area around the working element;
a switch element operatively coupled to the light emitting element; and
a locking element supported by the housing so as to be movable between a locked position and an unlocked position, the locking element configured to enable the motor actuator when positioned in the unlocked position and configured to disable the motor actuator when positioned in the locked position, the locking element further configured to operate the switch element when positioned in the unlocked position.

2. The power tool of claim 1 , wherein:
the switch element includes at least one switch; and
the switch element includes an actuation element associated with said locking element and movable to activate the at least one switch when the locking element is in the unlocked position.

3. The power tool of claim 2 , wherein:
the at least one switch includes two switches; and
the actuation element is movable to activate either of the two switches.

4. The power tool of claim 3 , wherein:
the two switches face away from one another; and
the actuation element is surrounding the two switches.

5. The power tool of claim 2 , wherein:
the switch element further includes a printed circuit board electrically connected to the light emitting element, and
the at least one switch is surface mounted to the printed circuit board.

6. The power tool of claim 5 , wherein the printed circuit board is movable relative to the housing to activate the at least one switch with the actuation element.
