Abstract
A pressure switch for controlling a switching element includes a spring-loaded piston operatively connected to the switching element and acted upon by a pressure fluid. A diaphragm separates the piston from the pressure fluid for providing a leaktight closure of the working parts of the pressure switch from the fluid stream, with a support ring surrounding the piston and being arranged axially between the diaphragm and a bushing by which the piston is guided in an axial direction.
