摘要： A novel gas control module switch mechanism includes a diaphragm means, a valve body, a piston means and a fastening means. The diaphragm means has a plurality of diaphragms and a seal plate sandwiched between a first and a second diaphragm. The first diaphragm has a center opening to prevent the first diaphragm from making direct sealing contact. Sealing is done through the seal plate. The seal plate is made of a soft material for obtaining improved sealing effect and longer durability. The valve body has a bulged ring around an opening plane and a bulged body ring for enhancing sealing effect when the seal plate making contact with the bulged ring.
