Patent

CA 2292855

A bistable actuator for residual-current devices, comprising a metallic lamina on at least one face of which, at at least one portion of the lamina, there is provided a layer of piezoelectric material, the end of the lamina at the piezoelectric layer being inserted with an interlock coupling in a supporting element, the opposite end being rigidly coupled so as to keep the lamina in a loaded position.

Un actionneur bistable pour dispositifs de courant résiduel comprend une strate laminée dont une face au moins, à tout le moins une partie de celle-ci, est recouverte d'une couche d'un matériau piézoélectrique, l'extrémité de la strate qui comporte la couche piézoélectrique étant insérée en même temps qu'un coupleur d'enclenchement dans un support, l'extrémité opposée étant couplée rigidement de manière que la strate reste en place.
