Patent ID: 7196280

Claim:
An electric switch ( 10 ) comprising: a bottom support ( 12 ) forming a contact-holder of insulating material that forms a cavity ( 24 ) in which at least two fixed electric contacts ( 30 , 30 B) are placed; an actuation member ( 54 ) which operates on a vertical axis (A) generally perpendicular to a base ( 28 A, 28 B) of the cavity ( 24 ); and a generally horizontal intermediate contact strip ( 14 ) of a conductive material that is interposed vertically between the actuation member ( 54 ) and the base of the cavity ( 24 ), that can be deformed elastically under a downward vertical action of the actuation member ( 54 ) from a stable, rest state in order to modify an electric connection between the at least two fixed contacts ( 30 – 30 B); said intermediate contact strip includes a front transverse movable contact arm ( 38 B) in the form of a generally horizontal band which, at rest, presses on an associated one of the fixed contacts ( 30 B) and which tilts about a horizontal transverse axis to break the electric connection between the at least two fixed contacts ( 30 , 30 B); said intermediate contact strip also includes two parallel and opposite branches ( 40 ) in the form of bands whose front ends are connected to the front transverse contact arm ( 38 B), each of the branches ( 40 ) is curved with a convexity oriented upwards, and the actuation member ( 54 ) of the switch comprises a horizontal flat bottom actuation face ( 62 ) in order to allow a generally elastic, symmetrical and simultaneous deformation of the contact strip ( 14 ).
