Abstract
In order to provide a reliable position indicator for a gear control, particularly for automatic transmission motor vehicles, use is made of reed switches (2). These may be mounted in a sealed housing and operable by a magnet (1) from outside the housing. The magnet (1) is movable by and with the gear control. The reed switches (2) may be mounted on a printed circuit board (3) and flux concentrators (4) are preferably provided between adjacent reed switches (2) to shield them until the magnet (1) is closely adjacent.
