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.
