Systems and methods for robust switching with the aid of switching contacts with a plurality of states and a common electrical reference

摘要

There are systems, methods and apparatuses for a robust determining a desired operating condition of a controlled device in response to the position of a more positions - actuator described. Two or more switching contacts are input signals, which represent the position of the actuator and between a reference signal and an intermediate signal are selected. A control logic unit then determines the desired state for the controlled device with the aid of the received input signals. The desired operating state, from an arbitrary number of operating states, which are defined by the input signals determined.
