PROBLEM TO BE SOLVED: To provide a pressure switch capable of setting a pressure across a very wide range under the pressure lower than the atmospheric pressure, finely tuning the set pressure, being excellent in fatigue resistance, constantness of sensitive speed, and high speed performance, capable of sensitively operating under a minute pressure difference, and capable of attenuating chattering without delay, and to provide a safe and simple decompressor whose failure is effectively suppressed, being manufactured at a low cost. SOLUTION: A pressure switch 1 comprises a conductive and elastic plate 3, an auxiliary elastic body 4 which is installed in the deflecting direction of the conductive and elastic plate 3 to contact the conductive and elastic plate 3, a set pressure adjusting member 6 which is installed on the side opposite to the deflecting direction of the conductive and elastic plate 3 and contacts the conductive and elastic plate 3 through the deformation action of the conductive and elastic plate 3 under the pressure higher than the set pressure, a first terminal 7 that connects to the set pressure adjusting member 6, and a second terminal 8 which can electrically connect to the first terminal 7 by way of the set pressure adjusting member 6 and the conductive and elastic plate 3.
