Breathing mask with face-contact actuated overpressure generating switch

A breathing mask, comprising:

• a mask body;
• a connection piece including a demand gas system for providing gas to an interior space of the breathing mask on demand said connection piece being inserted into said mask body;
• overpressure switching means connected to said demand gas system for switching said demand gas system from a stable switched off position into a switched on position for generating an overpressure in said mask interior space;
• actuating element means acting on said switching means at said connection piece for switching to overpressure generation in said switched-on position, said actuating element means including an actuating element extending out or said connection piece to a boundary area between said breathing mask body and a face of a mask user, said actuating element means for moving said switching means to said switched-on position when the breathing mask is donned by the wearer upon interaction between a portion of the surface of the face of the mask user and said boundary area, said actuating element being designed as a sensor mounted via a sensor hinge for movement of said sensor in a rocker-like manner, said switching member being designed as a rocker arm mounted via a switching member hinge, each of said sensor and rocker arm being tensioned in relation to one another by means of a tension spring acting on said sensor and a coil spring acting on said rocker arm.
