What Is a Pressure Switch?
A pressure switch is an electromechanical sensor that closes or opens an electrical contact once a preset pressure threshold is reached. Commonly calibrated in millibar (mbar) or bar, these switches:
-
Activate pumps, valves, or alarms when pressure rises above the “cut-in” setpoint
-
Deactivate systems when pressure falls below the “cut-out” setpoint
-
Prevent overfill, dry-run, or dangerous over-pressure conditions
Their compact design and robust materials make them ideal for daily use in hot, wet, or corrosive kitchen settings.
Key Applications in HoReCa Machines
-
Dishwashers & Hood Washers
-
Water Level Control: Pressure switches in under-counter, hood-type, and conveyor dishwashers (e.g., SMEG, Fagor, Colged, Elettrobar) monitor tank fill levels to prevent pump damage and overflows.
-
Steam & Rinse Cycles: Regulate steam generation and rinse pressure to ensure spotless, sanitary results.
-
-
Combi & Convection Ovens
-
Steam Injection: In combi ovens (Convotherm, Lainox), pressure switches verify boiler pressure before injecting steam, guaranteeing consistent humidity and cooking quality.
-
-
Boiling Pans & Pasta Cookers
-
Safety Cut-Off: On gas or electric kettles (Berto’s, Charvet) and pasta cookers (Giorik, Angelo Po), they shut off heat when water pressure drops too low, preventing dry-burn damage.
-
-
Glasswashers & Cupwashers
-
Pressure Regulation: Brands like Colged, Jemi, and Elettrobar rely on switches to maintain correct wash and rinse pressures, avoiding glass etching and ensuring energy efficiency.
-
-
Ice Makers & Refrigeration Units
-
Refrigerant Control: For R290 and R134a ice machines (Ice Tech, ITV), fan and high-pressure switches safeguard compressors by preventing operation outside safe pressure ranges.
-
-
Water Softeners & Soft Drink Systems
-
Pump Protection: In SMEG water softeners and beverage dispensers, pressure switches stop pumps if outlet pressure exceeds design limits, extending equipment life.
-
Choosing the Right Pressure Switch
-
Pressure Range: Match cut-in/out setpoints (e.g., 35/12 mbar for dishwashers, 1–3 bar for kettles).
-
Electrical Rating: Ensure compatibility (commonly 250 V, 10–16 A).
-
Connection Type: Select proper fittings (1/8″–1/4″ female, SAE, or hose end).
-
Temperature & Environment: Confirm operating temperature and material resistance.
Pressure switches are indispensable for safe, efficient, and consistent operation in HoReCa environments. By selecting quality, application-specific switches, professional kitchens can minimize downtime, protect equipment, and deliver impeccable foodservice results.
