Electric motor driven hand-held tool

An electric motor driven hand-held tool comprising a tool housing, a handle projecting from a first side of the housing, a motor located within the housing, an integrated switch unit (6), the switch unit including an electronic motor control unit (8) harm an actuator, a first manually operable switch member (4) located in the handle and adjacent to the integrated switch unit and operatively connected to the motor control unit and to which the motor control unit is responsive to power the motor, and a second manually operable switch member (14) located in the housing at a second side substantially opposite to the first side and operatively connected to the motor control unit via the actuator (10) and to which the control unit is responsive to drive the motor in one of a selected forward and reverse direction, characterised in that the second manually operable switch member (14) is located remotely from the switch unit (6) on an upward facing portion of the tool housing which can be seen by a user of the tool during normal operation of the tool, and a linkage arrangement (16) is pivotally mounted on a motor housing portion (3) of the tool housing so that manual actuation of the second manually operable switch member (14) causes the linkage to pivot and to actuate the actuator (10) and wherein the first manually operable switch member (4) and switch unit (6) are arranged such that when the first manually operable switch member (4) is acted on by a user of the tool so as to power the motor, the first manually operable switch member (4) holds the actuator (10) against movement by the linkage (16).

An electric motor driven hand-held tool comprising:

• a tool housing including a motor housing portion, an upper facing portion, a lower facing portion, and an interior circular boss;
• a handle, extending downward from the lower facing portion of the tool housing;
• a motor located within the motor housing portion and defining a longitudinal axis;
• an integrated switch unit including an electronic motor control unit and located in the handle;
• a first manually operable switch member projecting the through handle and operatively connected to the motor control unit, and whereby a tool user controls the speed of the motor;
• a second manually operable switch member projecting through the upward facing portion of the motor housing and whereby a tool user controls the direction of the motor, and
• a linkage arrangement including a central annular portion pivotably mounted on the interior circular boss within the tool housing, and a first arm extending from the central annular portion of the linkage and the second manually operable switch member is located on the first arm for operatively connecting the second manually operable switch member to the motor control unit and the pivot axis of the linkage arrangement is parallel to the longitudinal axis of the motor.
