1. A contactless switch module, comprising:

  • a plurality of magnets;

    a plurality of latching magnetic field sensing sensors;

    an actuator selectively operable to produce relative movement between the plurality of latching magnetic field sensing sensors and the plurality of magnets in response to manipulation by a user such that each of the latching magnetic field sensing sensors is proximal to a first respective one of the magnets when the actuator is in a first position and each of the latching magnetic field sensing sensors is proximal to a second respective one of the magnets when the actuator is in a second position, different from the first position; and

    a multi-channel switch controller having a plurality of input channels, each one of the plurality of magnetic field sensing sensors communicatively coupled to at least one of the plurality of input channels, the multi-channel switch controller configured to determine a respective current channel state for each one of the input channels, the current channel states being related to current sensor states of the plurality of magnetic field sensing sensors, the multi-channel switch controller further configured to find a current switch state based at least upon the current channel states and a logic.
