Abstract
This device comprises an enclosure and electric connections for connection, in a power supply circuit, with either one of two interchangeable electric power sources, as required. The enclosure delineates a housing accommodating either two primary cells together or a storage battery. A contact for connecting a terminal of one of the primary cells to a terminal of the other primary cell comprises a clamp that is deformable between a first configuration in which each one of two facing branches of the contact is positioned to connect one of said terminals by penetrating into an accommodating volume for accommodating the storage battery, and a second configuration in which the two branches are placed outside said accommodating volume which is left free.
