A gas burner control device including a biased closed, electromagnetically operated, fuel cutoff valve dependent upon electrical energy generated by a pilot burner-heated thermocouple to hold it open, and a biased open pressure responsive switch controlling the thermocouple-cutoff valve circuit, the switch being dependent upon a predetermined minimum gas supply pressure to close it and hold it closed, whereby either a drop in fuel supply below a predetermined minimum pressure or the extinguishment of the pilot flame effects closure of the fuel cutoff valve.
