Abstract
In a piezo-electric push button switch, a flexible printed circuit board is secured to terminals which are embedded in the housing, and the piezo-electric plate is supported by the flexible printed circuit board in such a manner that it is floated from the housing, whereby external impact or vibration is decreased, and in which an integrated circuit consisting of a resistor and a capacitor is incorporated in the switch body, to eliminate harmonics.
