<p>The device has a housing for a drive motor that drives a shaft of a final control element via gears, whereby at least one magnet has a functional connection to a fixed contactless switch. Two pin magnets of different polarity are arranged in fixed defined positions relative to the shaft of the final control element and functionally connected to the contactless switch, which produces a signal used to preset the motor's running direction. The device has a housing (2,3) for a drive motor (4) that drives a shaft of a final control element via gears (5), whereby at least one magnet has a functional connection to a fixed contactless switch (16), especially a Hall switch, in the housing so that by moving the magnet the contactless switch detects a pole transition and produces at least one signal for processing by a controller. Two pin magnets (11) of different polarity are arranged in fixed defined positions relative to the shaft of the final control element and functionally connected to the contactless switch, whereby the signal is used to preset the motor's running direction.</p> |
