Claim:
1. A gas appliance control device, in particular for appliances that comprise at least one gas tap having a safety valve that includes an electromagnet to be supplied by an electric current generated by a thermo-electric generator, the control device comprising: a manual-control means; a circuit arrangement that includes: a supporting structure, configured to be associated in a stationary way with respect to a gas tap, wherein the supporting structure includes at least one first part of stationary structure that defines a housing for at least part of the circuit arrangement, the first part of structure being designed to be housed within a body of a gas appliance, wherein the control means are designed for counting the time, and the device includes optical warning means; wherein the optical warning means comprise one or more light emitters operatively arranged within a casing of the device in the proximity of a passage thereof, and at least one light-guide element; wherein the light-guide element and a body of the manual-control means are made at least in part of a material designed to transmit light generated by the one or light emitters; wherein at least one of the light-guide element and the body of the manual-control means includes at least one peripheral wall generally inclined, for causing a light beam generated by the one or more light emitters to be reflected within said light-guide element and said body of body of the manual-control means; and wherein: the light guide element has an at least in part substantially frustoconical peripheral profile with a base thereof facing said one or more light emitters, in such a way that the light beam generated by the one or more light-emitters is reflected inside the light-guide element; and/or fitted or coupled in an axial cavity of the light-guide element is an end portion of the body of the manual-control means, said end portion being generally cylindrical, hollow and having an internal profile that includes a respective inclined wall, in such a way that the light beam generated by the one or more light emitters is reflected inside said cylindrical portion; and/or the body of the manual-control means has an end portion, fitted or coupled in an axial cavity of the light-guide element, and a flanged portion in a position generally opposite to said end portion, the flanged portion having an internal profile that includes a respective inclined wall, designed to reflect the light beam generated by the one or more light emitters towards an external peripheral profile of the flanged portion.
