The hall-switch has a current limiting circuit (5) and channels that are arranged between an input and an output. A polarity reversal protection diode (1) is provided behind the input. A power transistor (4) is provided as a bypass transistor for bridging a constant current source (2). Two hall sensors (7, 8) are provided in one of the channels, where outputs of the sensors control an intermediate transistor (6). Another hall sensor (11) is provided in another channel, where the hall-switch is closed with four connection cables. |
