Method of assembling a telephone keypad
摘要:
The invention is directed to a telephone structure that eliminates the need for fasteners to assemble a keypad and secure the keypad in place in the telephone. This is accomplished by a telephone that comprises a hollow housing (100) having a face portion (120) that includes an array of holes (122) and a keypad assembly (400) that comprises a sandwich of a static shield (430), button member (410), and switch contact member (450). The keypad assembly is assembled on the underside of the housing by means of a locating member (300) which has upstanding collar portions (325) that register in the holes of the face portion and depending pins (328) that register in holes in the members of the keypad assembly. The keypad assembly is held in place by a base member (200) that is joined to the housing and supports a raised pedestal (210) that extends into close proximity with the underside of the face portion and presses the keypad assembly against the face portion (FIG. 1).
