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.
