Single-level side-connection pressure switch, 46/30 calibration, for professional dishwashers. The pressure switch is the electromechanical component that senses the water level in the tank via a level tube connected to the pressure chamber: when the set threshold (46/30) is reached, it opens or closes the electrical contact controlling fill or drain, preventing both dry running of the pump and water overflow.

• Type: single level
• Connection: side
• Calibration: 46/30
• Application: professional dishwashers

Replacement becomes necessary when the dishwasher fails to stop filling at the correct level, when the pump runs dry, or when the pressure switch no longer switches contact despite the water level being reached.
