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.
