ABSTRACT:
A spring having three juxtaposed elastic blades connected to each other only at each end by two transversal portions. The central blade is cambered in a first direction and the two lateral or outside blades are cambered in an opposite second direction. The width of each blade diminishes to a minimum half-way between the middle of each end to equally distribute stresses applied to the spring, so that no lateral displacement of the spring will take place when it is compressed. The middle portion of the central blade has a protrusion adapted to make contact with an electrical component such as a battery. The two lateral blades each have a downwardly extending tongue at their center portion to bear against a bearing element, so there is electrical contact between the battery and the bearing element via the spring.
