ABSTRACT:
A sealed enclosure is provided for electrical circuitry to be located in a moist environment, as near a spa. The enclosure includes a housing of electrical insulating material, a display overlay adhesively bonded to the housing and covering certain openings in the housing for switches and displays, and a retaining bezel over the graphic overlay. Relief porting is provided in the bezel, and preferably also through a flange in a contiguous portion of the housing for assuring that water deposited on the display overlay will be drained away and thus not degrade the seal between the overlay and the housing.
