Hydro-electric pressure switches of type HED 5 are piston type pressure switches.
They basically consist of housing (1), installation kit with piston (2), compression spring (3), adjustment element (4) and micro switch (5)
The pressure to be monitored acts on the piston (2)
The latter is supported by the spring plate (6) and acts against the continuously adjustable force of the compression spring (3).
The spring plate (6) transmits the movement of the piston (2) onto the micro switch (5). This switches the electric circuit on or off, depending on the circuit set-up.
Notice:
In order to increase the life cycle, the pressure switch should be mounted with low vibrations and protected from hydraulic pressure surges.
