Abstract: A multidirectional control switch of the present invention is used in a variety of electronic apparatuses including a portable telephone and a personal digital assistant. A first switch contact of this switch outputs a first signal continuously varying as a top surface of a substantially disc-shaped operating member undergoes a sliding press along a locus substantially in arc form. With a stronger press, a second switch contact outputs a second signal. The multidirectional control switch has a simple structure and can be reduced in size because these two switch contacts are integrally formed, thereby eliminating a need to combine discrete elements.

Abstract: In a multi-directional operation switch, an operating disk, upon being pressed at its upper side, tilts to depress a elastic pressing member, thus making hard rings of the driving member to press a resistor sheet sequentially. This operation allows resistor layers beneath the resistor sheet to directly contact annular electrically conductive layers facing the resistor layers in a desired sequence, respectively. The multi-directional operation switch has a reduced height and can produce a number of switching signals according to desired angular directions of switching operations.
