Switching apparatus, electric field applying method and switching system

摘要

In a switching apparatus having a pair of electrodes including a first electrode and a third electrode, which are provided with a piezoelectric element therebetween and a pair of electrodes including a second electrode and a fourth electrode, which are provided adjacently to the pair of the first and third electrodes in a state where they are electrically insulated from the first and third electrodes, an electric field in a first direction is generated between the first electrode and the third electrode, and simultaneously an electric field in a second direction is generated between the second electrode and the fourth electrode.
