Abstract: Through an arrangement of linkages the rotary motion of the output shaft of a reversible gear motor is converted into linear motion to actuate a handle operating carriage and thereby also a pivotable operating handle of an electrical control device. A manually operable means for moving the carriage is also provided which includes means for automatically disconnecting the power to the gear motor upon application of a tool.
