ABSTRACT:
A method for producing keyboards by which the majority of manual labor can be omitted, and which primarily includes the following steps: molding keys from an injection mold in which the arrangements of the cavities thereof are the same as those of a commercial keyboard; moving the molded keys out of the injection mold and socketing the molded keys with a number of corresponding switches of a board by using a taking-out device; and pressing the molded keys tightly together with the corresponding switches so as to form a complete keyboard.
