Abstract
A contactless switch module, which is actuatable between a closed circuit position and an open circuit position, a plurality of magnetic field sensing sensors, and a plurality of magnets. The switch also includes a multi-channel switch controller. Each one of the plurality of magnetic field sensing sensors is communicatively coupled to an input channel of the multi-channel switch controller. The multi-channel switch controller is configured to determine a switch state based at least upon the respective states of its input channels.
