Abstract
An electromechanical horn warning system comprising a hollow body (2) having a cylindrical wall (8) closed by a bottom wall (9) and a flanged edge (12). At least one bobbin (3) abuts on the bottom wall (9) of the hollow body. An elastic membrane (6) is provided with at least one mobile core (7) that is fixed to the flanged edge (12) of the hollow body. At least one contact breaker (4) having a support (22) and a spring (23) are provided with electric contacts (27, 28). An insulating plate (5) is sandwiched between the support (22) and the spring (23), and is provided with at least one layer (31, 32) of resistive silk-screen ink.
