Abstract
A power tool includes a hollow housing defining a handle with an external wall. A motor is disposed in the housing. A switch is pivotally mounted in the handle about a first axis for actuating the motor. The switch has a first locking abutment. A latch is located adjacent the switch and is pivotally mounted in the handle about a second axis generally parallel to the first axis for movement back and forth between an engaged and a disengaged position. The latch has a second abutment for engaging the first abutment and preventing the switch from being actuated. The latch when pivoted to engage the first and second abutments applies a force vector generally intersecting the second axis.
