Abstract

A low-voltage power switch, which comprises an actuator provided with actuation means which are suitable to act on the kinematic mechanism for opening/closing the contacts of the switch and means for pre-loading the actuation means. The particularity of the low-voltage power switch according to the invention consists of the fact that it comprises at least one dimorphic piezoelectric element whose deformation is suitable to allow the release of the actuation means.
