Abstract

The present invention relates to a pressure switch having a manually operated safety microswitch, characterized in that it comprises a bottom body, defining in its inside a chamber communicating with a fluid to be controlled, and associated with a top cap, which supports an operating microswitch. The chamber is closed by a membrane, preferably made of a silicone material, provided with an O-ring and coupled to a steel membrane, with a driving tappet assembly which is directly formed on the latter membrane and operates on a washer element, which is counter biassed by a first counterbiassing spring and operates on a push-button of the operating microswitch, a safety microswitch being moreover provided, which can be manually operated or re-armed, and cooperating with a pin element extending from the washer. <IMAGE>
