Piezoelectric switch.

摘要

A piezoelectric switch (20) including a casing (22) for receiving an external mechanical force, a piezoelectric ceramic (24) for sensing the external mechanical force received by the casing and converting the force to an electrical signal, the ceramic having one side connected to the casing and another side having both the positive (240) and the negative (242) poles, a conductive rubber (26) connector disposed adjacent to and in contact with the ceramic (24) for conducting the electrical signal and a printed circuit board (28) disposed adjacent to and in contact with the conductive member (26) for receiving and processing the conducted electrical signal received from the ceramic (24) and for preventing any electrical signals from passing from the circuit board (28) through the conductive member (26) to the piezoelectric ceramic (24).
