Abstract
A pressure responsive switch having an atmospheric pressure chamber including electrical contacts which are sealed hermetically by a flexible pleated cover whereby the flexible pleated cover deforms in accordance with the expansion and contraction of the atmosphere in the atmospheric pressure chamber. The alteration of the temperature surrounding the atmospheric chamber provides for the expansion and contraction of the atmosphere with the atmospheric pressure chamber and the pleated cover maintains the atmospheric pressure constant within the pressure chamber.
