Abstract
A limit switch assembly includes a housing having a first end, a second end, an inner surface that defines an inner volume and a spring engagement surface, and an outer surface. A limit switch disposed within the inner volume includes a threaded bushing section at least partially extending from the first end. A spring within the inner volume surrounds the bushing section, and engages the limit switch and the spring engagement surface. A calibration nut threaded onto the bushing section engages the first end of the housing. A seal divides the inner volume of the housing into a first volume and a second volume. A drain hole formed in the housing fluidly communicates the first volume to a surrounding environment. A terminal assembly connected to the second end of the housing seals the second volume from the surrounding environment.
