    摘要: The molded key switch shield assembly (100) includes a molded member (104) and a key switch overlay (102). The molded member (104) includes a shield metallization pattern (136) which substantially covers major portions of both the first (138) and second major surfaces (140) of the molded member (104). The molded member also includes a metallization pattern (124) having a plurality of key switch locations (118) which can be shorted by conductive locations (112) on key switch overlay (102).

    摘要: A radio frequency switch assembly (120) is mountable between an antenna port (110) and a detachable antenna (130) of a radio communication device assembly (100) to provide an interface for a radio frequency accessory. The switch assembly (120) has a radio interface port (123), a radio frequency accessory port (125), and an antenna interface port (127), and associated contacts (207, 216, 223). A mechanical switch alternatively interconnects the radio interface port (123) with the radio frequency accessory port (125) or with the antenna interface port (127). Preferably, the switch includes a conductive probe (213) that continuously engages the radio interface port contact (207) while being slidable to electrically interconnect with the antenna interface port contact (223) or with the radio frequency accessory port contact (216).
