Patent ID: 8723060

Claim:
A power tool, comprising: a housing; a trigger configured for movement relative to the housing between a first position and a second position; a switch provided in the housing which is coupled to the trigger and a power source, wherein actuating the trigger from the first position to the second position controls the switch thereby allowing power to flow from the power source to operate the power tool; a lock-off mechanism provided on the housing for actuation between a locked position and an unlocked position and comprising: a locking pin adapted for movement between a first position blocking movement of the trigger relative to the switch and a second position in which movement of the trigger relative to the switch is not prevented by the locking pin; a release button coupled to the locking pin and provided on the housing for movement between a first position corresponding to the first position of the locking pin and a second position corresponding to the second position of the locking pin; and a biasing member that directs the locking pin into the first position blocking movement of the trigger, wherein pressing the release button in a direction into the housing causes the locking pin to rotate into the second position that does not block movement of the trigger.
