10.4. Switching

behaviour

The following diagram clarifies the switching behaviour of the pressure switch.
The contact closes (type of contact: N.O.) when exceeding the switch point or
falling short of the window point. It opens only again after exceeding the window
point plus the hysteresis or falling below the switch point minus the hysteresis. An
LED signals the switching status of the pressure switch.
