Abstract
A system comprises an industrial enclosure, first and second magnetic controls in close proximity to one another, and a magnetic field sensor. The first and second magnetic controls are secured to an outer surface of a cover of the industrial enclosure without penetrating an inner surface of the cover. The magnetic field sensor within the industrial enclosure senses a characteristic of the first magnetic control and a characteristic of the second magnetic control, and generates a signal corresponding to each of the characteristics. The signal is used by a controller to identify a setting of each of the first and second magnetic controls. Each of the first and second magnetic controls are positioned proximate to one another and each has a polarity and/or magnetic field strength that does not interfere with the detection of the others respective characteristic.
