Abstract

An elastic electrical contact device consisting of at least one mobile contact carrier and a fixed contact carrier comprising at least two conductors, characterized in that the mobile contact carrier consists of a flat base (1) made of plastic material, said base has at one end a removable key head (2) and at the other end a filiform V-shaped spring (3) that is round or angular in section and has a tip adapted to engage in an opening (4) of the flat base while its body is guided by projections of the base (5, 6), the base has at its other end protrusions (7, 8) protruding from the flat base; the fixed contact carrier consists of a receptacle (10) that is sunk in a plate (base plate 9) and has grooves (11, 12) to guide the flat base, said grooves having a window (13, 14) toward the base. Outside at the bottom of the receptacle, the elastic projections (7, 8) of the flat base engage in said grooves and can move between the stops (15 and 16), a cylindrical compression spring (19) that goes on the bottom of the receptacle and in the recesses (17 and 19) of the flat base (1) and at least two spring threads (20, 21) that are of round or angular section and that cross the V-shaped spring (3) forming angles straight and guided in guides (22, 23) against which they rest laterally, and in hooks (24, 25, 26) so that they do not rise from the base plate and that they are on one side, ending said springs (20, 21) directly on the fixing devices (27 to 37 or 38).
