Abstract

The present invention relates to a touch pressure switch, including a manually operated safety microswitch, characterized in that it comprises a bottom body defining a chamber, in communication with a fluid to be controlled, and being associated, through a blade contact bearing ring element, with a top cap. The chamber is closed by a membrane provided with an O-ring and coupled to a steel membrane, provided with a driving tappet assembly directly formed on this membrane and operating on a washer element, which is counter-biassed by a first biassing spring and being adapted to operate on at least a blade contact which is supported by the contact bearing ring element, a safety microswitch being moreover provided, which can be manually operated or rearmed, and which cooperates with a pin element extending from the washer. <IMAGE>
