Danfoss KPI pressure switches are used for regulating, monitoring and alarm systems in industrial applications.
The KP series are suitable for plant in connection with liquid and gaseous media. They are fitted with a single-pole switch changeover (SPDT). The position of the switch depends on the setting of the pressure control and the pressure in the connector.

KPI features
Danfoss KPI pressure switches are designed so that the bellows moves in the same proportion as the pressure change.
To ensure a snap function on contact changeover, an omega spring is located between bellows and contact system.

The design of KPI pressure switches gives the following advantages:
• High contact load
• Ultra-short bounce times
• Vibration-proof in the range 0-1000 Hz, 4 g (1 g = 9.81 m/s2)
• Long operating life
• Can be used for both liquids and gases
• Small dimensions – Easy to mount in panels
