摘要

A COVER MEMBER (1) FOR AN ILLUMINATED PUSH BUTTON SWITCH CAPABLE OF PROVIDING THE HARD TOUCH WITH FINGERS WHEN IT IS INCORPORATED IN A SWITCH UNIT AND FACILITATING FORMATION OF A SYMBOL/CHARACTER DISPLAY SECTION (23) EXHIBITING DISTINCT DISPLAY AND AESTHETIC PROPERTIES. IN THE COVER MEMBER, KEY TOPS (20) EACH ARE PROVIDED AT A DISTAL END THEREOF WITH A HARD RESIN SECTION (21). THE RESIN SECTION IS INTERGRALLY MOUNTED THEREON WITH A RUBBER SECTION (22) AND THEN THE SYMBOL/CHARACTER DISPLAY SECTION IS FORMED ON A FLAT SURFACE OF THE RUBBER SECTION. THE RUBBER SECTION IS FIXED ON THE FLAT SURFACE THEREOF TO A MOVABLE SECTION (12) OF A SUBSTRATE (10). SUCH CONSTRUCTION PROVIDES A USER WITH A SATISFACTORY FEELING IN OPERATION, EFFECTIVELY PREVENTS WEARING OF THE SYMBOL/CHARACTER DISPLAY SECTION, PROVIDES THE SYMBOL/CHARACTER DISPLAY SECTION WITH AN AESTHETIC APPEARANCE WITHOUT ANY DEFECT AND ENSURE INCREASED DURABILITY OF THE COVER MEMBER, RESULTING IN A COMMERCIAL VALUE OF THE COVER MEMBER BEING HIGHLY INCREASED.
