Abstract
An electric motor driven hand-held tool, such as a drilling, hammering or screw driving tool having a tool housing within which is located an integrated switch unit (). The switch unit () includes an electronic motor control unit (), a first actuator which is actuated by a manually operable power member () and to which the control unit is responsive to power the motor and a second actuator () which is actuated by a manually operable forward/reverse member () and to which the control unit is responsive to drive the motor in a selected forward or reverse direction. The forward/reverse member () is located remotely from the switch unit () on a portion of the tool housing which can be seen by a user of the tool during normal operation of the tool. To facilitate this a linkage arrangement () is provided for actuating the second actuator () in response to a manual actuation of the forward/reverse member (). The linkage () is pivotally mounted on a closed end of a jam pot motor casing (). The linkage comprises a central annular portion () pivotally mounted on a boss () formed on the motor housing (), a first upwardly extending arm () on which the forward/reverse lever () is formed and a second downwardly extending arm () which engages the second actuator ().
