ABSTRACT:
An appliance switch includes a base housing having a pair of trough-like recesses and a cover member having a pair of cylindrically-shaped members. The cylindrically-shaped members are arranged so as to be received snugly within the respective pair of trough-like recesses in order to provide a stabilized engagement. A sealing member consisting of an inverted U-shaped flange is formed on the outer surface of the cover member for creating a tighter sealing contact between the cylindrically-shaped members and the trough-like recesses during the period of switch actuation.
