Abstract
Abstract A remote control lever module comprising a support including a bearing and a lever including a shaft pivotably supported by the bearing for oscillation about the shaft axis between a nonactuating position and actuating positions. The lever further includes an actuating arm extending from the shaft at an angle thereto for moving the shaft between the nonactuating position and the actuating positions and a return spring acting on the lever when the shaft is in the actuating positions to urge the shaft to the nonactuating position. Magnets are fixed on the shaft and movable therewith to provide a movable magnetic field of varying strength in an effective zone adjacent one side of the shaft. A magnetic field sensor is fixed to the support adjacent to the shaft in the effective zone of the magnetic field and operative to sense the variation in strength of the magnetic field at various positions of the shaft and to form a readable output signal proportional to the variations for indicating the angular position of the shaft. The lever module may also have a lever force switch engageable by the shaft to close the switch when the actuating arm urges the shaft into the actuating positions.
