Abstract: An actuator for a lumbar support device possessing a symmetrical housing in that key holes are present on both sides of such housing. The present invention's housing, with key hole slots diametrically opposed on one end, allows the actuator to be installed more easily in any orientation, in either driver or passenger side seats. With the dual key hole housing, the extra time and effort associated with ensuring that the correct side of the housing is being used is eliminated as the dual key holes allow the tension cable wire and tension cable wire end to be inserted into either side of the housing during assembly of the lumbar support system. The elimination of this concern will save valuable time and money in the actuator assembly process.

Abstract: A control lever assembly, particularly for controlling marine propulsion systems, having first and second signal outputs controllable simultaneously by a single lever. The lever is journalled for rotation about a lever axis relative to a body, and can be shifted axially between engaged and disengaged positions. An interrupter driver has driving engagement structure and responds to lever rotation and cooperates with the first signal output. An interrupter driven structure has driven engagement structure which is engageable with the driving engagement structure when the lever is in the engaged position, and is disengageable when the lever is in neutral and is shifted axially. When engaged, the second signal output is responsive to primary rotation of lever. Selector structure permits the axial movement only when the lever is in neutral, and simultaneously permits rotation of the lever to control the first signal output with no corresponding change in the second signal output.
