Abstract
A control surface is positioned on the top horizontal surface of the case of a personal radio. A flexible printed circuit connects the control surface to the internal electronic circuits of the personal radio. A printed circuit board is connected to the flexible printed circuit by a connector soldered to both the flexible printed circuit and the printed circuit board. Some of a plurality of electrical pathways disposed on the printed circuit board are grouped into conductive pairs, while other pathways connect the conductive pairs to the connector. A keypad formed of a sheet of resilient material encases a surface of the printed circuit board. Molded into the keypad are resilient hollow keys, the hollow of each of which contains a conductive pad. When a key of the keypad is depressed, the conductive pad associated with that key makes contact with predetermined ones of the conductive pairs of the printed circuit board, completing an electrical circuit. The completed electrical circuit is detected by the electronic circuits of the personal radio and used to program the functions of the radio.
