Abstract
A push-button assembly (10) is constituted by a push-button (12) having a side wall outer surface located adjacent to a side wall inner surface of a surrounding body (14). In the assembly, at least one of the side wall surfaces is recessed (22; 22a, 22c; 22b, 22d), thereby reducing the contact area of the opposed surface areas likely to be adversely affected by stickiness.
Claims2
A push-button assembly, for use in a game playing machine, comprising a push-button movable in a predetermined direction relatively to a surrounding body;
- the surrounding body including a decorative bezel which projects laterally outwardly of and is located at one end of a push-button switch mounting whose other end is adapted to permit mounting of a switch thereto, the push-button including a cap which is movable in said predetermined direction within the decorative bezel and a spring-biased support which is movable in said predetermined direction within the push-button switch mounting to permit operation of the switch thereby, and an outer surface of a side wall of the push-button being located adjacent to an inner surface of a side wall of the surrounding body;
- characterised in that each of said side wall surfaces is formed with a plurality of slanted grooves, each of said slanted grooves being inclined with respect to said predetermined direction, and said pluralities of slanted grooves being opposed to one another and being inclined in opposite directions in order to reduce stickiness resulting from a liquid being spilled and penetrating between said side wall surfaces.
