A bistable actuator for residual-current devices, including a lamina having at least one face, a first end, and a second end, and configured to actuate from a first stable position to a second stable position; at least one layer of piezoelectric material provided on the at least one face of the lamina at the first end of the lamina, and configured to stimulate the lamina to shift from the first stable position to the second stable position in response to an electrical activation signal; and a support element including an interlock coupling, and configured to support the first end and the second end of the lamina, wherein the interlock coupling is configured to interlock the first end of the lamina to the support element, and the second end of the lamina is rigidly coupled to the support element in order to keep the lamina in the first stable position.
