Rotary gas tap with an electric switch

摘要

The rotary gas tap (1) installed in a cooker has, assembled on its operating shaft (50), an electric switch (2) covered with a protective cap (11). The shaft (50) of the rotary gas tap effects a translation for the closing and opening of the switch (2), which is formed by a metallic plate-contactor (30) fitted into an insulating casing-support (20) fixed concentric to the tap shaft (50), and displaceable axially with it. The plate-contactor (30) bears at least one elastic tab (33) as an electric contact for its closing against an "electric mass" of the metallic body (40) of the tap. The only connection terminal (31) extended in a radial position is connected to a voltage signal (Vs) wire originating from the control unit of the cooker.
