Abstract: A portable electronic device (1) of the present invention includes an antenna duplexer (10), an antenna (20), a cover (40), and a button (42). The antenna duplexer (10) performs a switching between transmit and receive signals. A switch (30) is electrically connected between the antenna duplexer (10) and the antenna (20). The button controls the opening and closing of the switch. By pushing the button between two positions, a user connects or disconnects the switch, thereby confining entering calls for the electronic device mobile phone function. Other functions of the mobile phone thus will operate without interruptions when the switch (30) is opened.

Abstract: A multiple key assembly (100) includes a multiple key including a central key (1) and four key segments (2) separated from each other, a base member (4) having a base (42), a circular platform (44), a plurality of connecting parts (46) flexibly connecting the circular platform with the base and a PCB (6). A plurality of contacts (49) is provided on bottoms of the circular platform and the connecting parts, and the PCB provides a plurality of contact pads (62) corresponding in position to the contacts on the base member. During assembly, the multiple key is first mounted on the base member and then both are secured to the PCB with the plurality of contacts of the base member suspended above the corresponding contact pads on the printed circuit board. If desired, an elastic spacer (3) and/or a key sheath (5) can be included.
