ABSTRACT:
Control device for at least two luminous condition indicating signals (30, 41) mounted on a domestic electrical appliance provided with a quick opening adjustable thermostat (2) which passes over center. An insulating support (13, 14, 15) receives a thermostat arm (11), a blade (16) forming a fixed contact, a movable blade (7) provided with a flexible tongue (20) on which bears an insulating plug (22) controlled by a rotatable screw (10) permitting obtaining a predetermined temperature, and another movable blade (8) fixed to the movable blade (7) and whose free end bears against the fixed contact as well as an insulating partition (9) fixed to the bimetal (6) and controlling the movable blades (7 and 8). The blade forming a fixed contact (16) and the movable blades (7 and 8) are fixed to the insulating support, connected respectively to electrical terminals by electrical connections (3, 4) and supply the two luminous signals (30, 41). A resilient conductive blade ( 48) having a free end (47) and an end (49) fixed to the insulating support (13, 14, 15), is connected electrically by this end to the terminal (19) and in engagement with the flexible tongue (20) by a bearing member (51). A conductive element (44) is fixed on the insulating partition (9), is connected by an electrical connection to one of the two luminous signals and is adapted to come into contact with the end (47) when the heating temperature is higher than the predetermined temperature.
