Abstract
An enclosed proximity switch assembly includes a top enclosure and a bottom enclosure that are coupled to form an interior volume. A shaft protrusion upwardly extends from a top surface of the top enclosure, and an interior bore portion having an enclosed volume is defined within the shaft protrusion to form a portion of the interior volume. A first end of a vertical shaft is rotatably disposed within the interior bore portion such that the shaft rotates relative to the top and bottom enclosures. A samarium cobalt target magnet is coupled to the shaft, and the target magnet interacts with a samarium cobalt driver magnet within a proximity switch when the target magnet is rotated within a predetermined distance of a top portion of the proximity switch. The interaction causes a switch to move from a first state to a second state, or vice versa.
