The contact system in KP pressure switches has
a snap function. This means that the bellows
is active only when the cut-in or cut out value
is reached.
The bellows is connected to the pressure of the
controlled plant via the connector (7).
Danfoss KPI pressure switches are designed
so that the bellows moves in the same
proportion as the pressure switches change.
To ensure a snap function on contact change
over, an omega spring is located between
bellows and contact system.
