A button assembly for selectively actuating a switch. The button assembly ( 10 ) includes a button member ( 16 ) for being mounted in an opening of a housing. The button member ( 16 ) is fabricated of a resilient material and defines an outer surface ( 38 ) that can be depressed to bring the button assembly ( 10 ) into contact with the switch for purposes of actuating the switch. The button assembly ( 10 ) also includes a compression ring ( 26 ) for being received in a bore ( 28 ) provided in the button member ( 16 ) whereby the compression ring ( 26 ) compresses the button member against the edges of the housing that define the opening in the housing creating a substantially liquid impervious seal and holding the button assembly ( 10 ) in place in the opening.
