ABSTRACT:
A control knob for turning on or off a burner of a kitchen gas stove, the knob including a cam-faced spur on a side of the knob shank which travels behind a stationary stop mounted on the stove when the knob is being turned to shut off the gas, the stop preventing the knob to be turned on again unless the knob is first pushed axially so the spur clears the stop, the construction preventing children to readily turn the gas on.
