ABSTRACT:
A tab (2) obtained from plate (1) from which it emerges through a process which includes a first shearing phase, with which the elongated vent hole (6) is carried out, a second coining phase with which the impression (4) and the protruding contact button (5) are obtained around the elongated vent hole (6), a second shearing phase with which the work hardened--reduced thickness metal is cut along the line which defines the tab (2) which is inflected and made to protrude from the surface (9) of the plate (1) on the side of the impression (4). On the three sheared off sides, the tab (2) is smaller than the impression (4) to allow it to deflect freely in the said impression (4) when it is undergoing stress.
