Pressure switch cup Stalgast C012364

A pressure switch cup is the sealed chamber that converts steam or gas pressure into the mechanical movement that opens or closes an electrical contact. In professional catering equipment—steamers, combi ovens, pressure fryers and boilers—the cup senses the build-up of pressure inside the cooking vessel. When the pressure reaches the set point, the cup flexes, triggering the switch that either cuts power to the heating element or opens a relief valve. This cycle maintains the exact pressure needed for consistent results, whether steaming vegetables, poaching fish or pressure-frying chicken. Without a properly functioning cup, the appliance cannot regulate its internal pressure, risking under-cooked food or over-pressure faults.

The operator does not interact directly with the cup; it is installed inside the appliance during routine maintenance or repair. Once fitted, the cup remains in place, responding instantly to every pressure change without further adjustment. Its role is passive but critical: it translates the invisible force of steam or gas into the electrical signal that keeps the cooking process safe and repeatable.

This Stalgast pressure switch cup 90 is a direct replacement part, manufactured to match the original dimensions and pressure ratings of the equipment it fits. It is used in a range of professional catering appliances where pressure control is essential for performance and safety.

Cleaning is not required for the cup itself, as it is a sealed component. Regular inspection of the surrounding pressure system—valves, seals and electrical contacts—ensures the cup continues to function accurately. Always replace the cup if signs of deformation, cracking or leakage are detected, as these indicate the material has reached the end of its service life.

The product is listed in the Stalgast spare parts catalogue under pressure control components for commercial catering equipment.
