ABSTRACT:
A switch assembly having switch contacts located in a lower housing component and having a movable actuator located in an upper housing component and extending downwardly into the lower housing component through a sealing gasket located between the two housing components. The gasket prevents liquid spilled into the upper housing component from leaking into the lower housing component and shorting out the switch contacts. Drain openings are formed in the upper housing component and prevent the liquid from rising to a level where the liquid could leak past the sealing gasket. The actuator includes a manually operable button which is shaped to direct spilled liquid toward the drain openings. In addition, fin-like portions of the gasket extend beneath the drain openings to deflect the discharged liquid away from the outer side of the switch assembly.
