ABSTRACT:
A safety control switch comprises a slide base movably mounted on the housing of a gas-fired ignition device, a push button positioned in a through hole of the slide base, a brake block fixed to the push button for inserting into a space between the slide base and the housing, and a locking piece movably mounted on the slide base and engaged with the through hole of the slide base, the locking piece being moved relative to the slide base between a first position to prevent the push button and the slide base from being operated by blocking 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.
