Abstract: <P>PROBLEM TO BE SOLVED: To provide a press-button switch which is versatile in operability responding to increased functionality of electric equipment.  <P>SOLUTION: The complex press-button switch 8 is provided with an analog switch 15 generating an analog input signal corresponding to the quantity of depression of a resin key top 9 and an on/off switch 16 generating an on/off input signal when the resin key top is depressed exceeding the above quantity of depression, both of which are arranged under the resin key top. By this set up, versatile operability is obtained by alternatively using an analog operation and an on/off operation. Since the both switches 15 and 16 are provided under the resin key top 9 which is a single operation key, it is not necessary to provide the electric equipment with separate switches. Consequently, further miniaturization is realized, and a troublesome operation that an operator must alternatively use the different press-button switches becomes unnecessary, and therefore the complex press-button switch is convenient.  <P>COPYRIGHT: (C)2004,JPO
