Hydro-electric pressure switches type HED 1 are piston pressure switches.
Type HED 1 pressure switches have the task of switching on or off an electrical circuit dependent on pressure. The live electrical terminals are covered by an isolating strip.
Adjusting of the switching pressure
To adjust the switching pressure, the name plate must first be removed and the locking screw loosened.
The switching pressure is set by rotating the adjustment screw. Finally, the adjustment screw must be secured by the locking screw and the name plate refitted.
