  • Methods of manufacturing a push button switch cover
    Patent number: 6625876
    Abstract: A method for manufacturing a push button switch cover includes providing a cover substrate that is formed on a front surface thereof with at least one key top and on a rear surface thereof with at least one pressing projection in a manner that corresponds to the key top, and applying an adhesive to the pressing projection to form an adhesive section on the pressing projection. The cover substrate is carried to a dish-shaped metal spring feed position while keeping the pressing projection facing up, and a dish-shaped metal spring is pressed onto the pressing projection corresponding thereto, while aligning a central portion of the pressing projection with an apex of the dish-shaped metal spring, whereby the dish-shaped metal spring is bonded to the pressing projection through the adhesive section.

  • Push button switch cover and method for manufacturing same
    Patent number: 6388218
    Abstract: A push button switch cover capable of enhancing positional accuracy between a cover sheet and dish-shaped metal springs, thereby highly improving keying characteristics and reducing manufacturing cost. The cover sheet is provided on a front surface thereof with key tops and on a rear surface thereof with pressing projections in correspondence to the key tops. The dish-shaped metal springs are each bonded to a respective one of the pressing projections by an elastic adhesive section while keeping an apex of the dish-shaped metal spring abutted against a central portion of the pressing projection.
