ABSTRACT:
A pressure switch wherein electrode plates are provided on both sides of a pressure conductive rubber plate. The pressure switch is interposed between a body and a receiving block slidably fitted to the body so that both electrodes may be connected with each other by connecting the rubber plate into conductive state to obtain an electric signal across the electrodes. The pressure applied to the rubber plate is regulated by a variable spring.
