Self-powered remote control device, electrical apparatus and installation comprising same

A self-powered remote control device comprising:

• transmission means for transmitting a signal for controlling an electrical apparatus;
• a power conditioning circuit connected to the transmission means;
• an electric power generator comprising at least one piezoelectric element for supplying electric power to the power conditioning circuit;
• control means for controlling the electric power generator, comprising:
• striking means for generating a calibrated amount of mechanical energy for striking the piezoelectric element with a predetermined second force, thereby mechanically stressing the piezoelectric element to generate electric power;
• and
• actuating means actuatable by a first force for actuating said striking means, wherein a magnitude of the second force is not a function of a magnitude of the first force, wherein
• the piezoelectric element comprises a housing, a flexible metal support and a pad of piezoelectric material located on one face of said support, and the flexible metal support is loosely held within the housing.
