Input arrangement for e.g. mobile telephone, has evaluation circuit determining position of magnets relative to sensors and outputting control signal, where arrangement includes supply conditions with respective operating energies
Input arrangement for e.g. mobile telephone, has evaluation circuit determining position of magnets relative to sensors and outputting control signal, where arrangement includes supply conditions with respective operating energies
The arrangement (40) has a sensor device with magnets (41) that are movably arranged, and a set of sensors (42a-42d) e.g. hall sensors, for measuring magnetic fields in a supply condition with an operating energy. An evaluation circuit (43) is coupled with the sensor device to determine a position of the magnets relative to the set of sensors and to output a control signal based on the sensors, where the arrangement includes another supply condition with another operating energy. The circuit deactivates one of the sensors at a time interval in the latter condition. An independent claim is also included for a method for operating an input arrangement for an electronic device.
