| 摘要 |
The invention relates to a piezoelectric switch comprising a first piezoelectric element, an operating unit that can move transverse to the principal plane of the first piezoelectric element for exerting a force on the first piezoelectric element which deforms the piezoelectric element and electrical connecting means for conducting signals generated by the first piezoelectric element when the first piezoelectric element is deformed, whereby a second piezoelectric element is positioned that is mechanically linked to the operating unit in such a way that when the operating unit is operated, a force mechanically deforming the piezoelectric elements is exerted on at least the first and second piezoelectric elements and the at least second piezoelectric element is provided with electrical connecting means for conducting the signals generated by the second piezoelectric element when the second piezoelectric element is deformed, with the electrical connecting means of each piezoelectric element being at least partially separated from each other. |
