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.
Claims18
