ABSTRACT:
An alternate switch actuating mechanism for an electric drill or similar tool which permits the tool to be used in either a portable or stationary operation. The tool has a first handle that includes a first switch actuator for operating the tool and a second detachable handle which carries a second actuator for the switch. The second actuator is constructed so as to directly engage the first actuator to permit simplicity of operation and ease of disassembly for stationary operation. A lock is provided for precluding accidental actuation of the second actuator. The device also includes a reversing switch and an interlock which prevents actuation of the reversing switch when the drill is energized.
