KEY TOP PANEL OF PUSHBUTTON SWITCH

摘要

PURPOSE:To provide a key top panel of a pushbutton switch which has a simple structure, allows a smooth operation for pushing each key top even when miniaturized, and has a waterproofing function. CONSTITUTION:An upwardly projecting portion 21 is formed in position on a film plate 20 made of resin films and a synthetic resin 23 is packed in the projecting portion 21 and is cured and integrated with the projecting portion 21 to form a key top 50. A curved projecting portion 25 which projects downwards from the surface of the film plate 20 is formed on the outer periphery of the portion of the film plate 20 where the key top 50 is formed, in such a way as to surround the key top 50. When the key top 50 is pressed, only the curved projecting portion 25 of the film plate 20 is deformed and the portion outside it is not pulled at all, so an operation for pressing the key top is facilitated.
