ABSTRACT:
A method and system, which minimize contact bounce during closure of a piezoelectric bender switch, control the switch closure to occur when the movable contact is traveling at a low velocity, when the phase of oscillation of the movable contact tends to press the contacts together after closure, and when the magnitude of the closing force developed in the first piezoelectric layer is only a fraction of its maximum value.
