Abstract:
1. A safety control switch for a gas-fired ignition device comprising: a slide base movably mounted in a track of a housing of the gas-fired ignition device which triggers release of ignitable fuel once in slided position; a push button positioned in a through hole of the slide base, in a depressed state creates a spark by completing an electrical circuit, to ignite released fuel; a brake block fixed to the push button configured for inserting into the track to fill a space between the slide base and the track; and a locking piece movably mounted on the slide base and engaged with the through hole of the slide base, the locking piece is arranged so as to be moved relative to the slide base between a first position to prevent the push button and the slide base from being operated wherein a portion of said locking piece is located to prevent the push button from passing through the through hole and a second position to allow the push button and the slide base to be operated by removing the blockage of the through hole; wherein the locking piece is returned to first position through the force exerted by a tension loaded mechanism when there is no external force acting thereon.
