Abstract
A combination gear-selector, sensor device for use with vehicle transmissions having a plurality of gear positions and certain special gear functions and being controlled by an electronic circuit includes a shift lever having a first, square magnet which, when moved over distinct gear position sensors, indicates selection of a certain gear. A rod coaxially disposed within the shift lever has a second, rectangular magnet, displaced to one side of the first magnet, which when vertically moved over a first function sensor, indicates selection of that function which can be to skip a gear. A coaxial tube surrounds the rod member within the shift lever and has a third, rectangular magnet, displaced to an opposite side of the first magnet, which can be moved over a second function sensor to indicate selection of a second special function. The three magnet elements are oriented in an adjacent but opposing polarity relation and the sensors are polarity sensitive to prevent inadvertent indication by the wrong magnet, sensor arrangement. The special functions can only be selected in an active gear position due to the rectangular shape of the second and third magnets.
