ABSTRACT:
An electric gas lighting device including an ignition circuit for generating sparks at at least one burner and connected to a supply line, supplying a supply voltage, via enabling means for alternatively enabling/disabling spark generation when connected/disconnected to/from a reference potential line; the enabling means are defined by a secondary winding of an isolation transformer interposed between the supply line and the ignition circuit; a first terminal of the secondary winding of the isolation transformer is connected to a first terminal of hand-operated switch means, a second terminal of which is connected to the reference potential line; and the ignition circuit also includes a discharge generating circuit, a first node of which is connected to the reference potential line, and a second node of which is connected to a second terminal of the secondary winding of the isolation transformer.
