Windust Hydraulics stock the HED8 pressure switch, manufactured in Germany by Rexroth.
The hydro-electric pressure switch type HED 8 is a piston type pressure switch. It basically comprises of housing, installation kit with piston, compression spring, adjustment element and micro switch. If the pressure to be monitored is below the set pressure, the micro switch is operated. The pressure to be monitored is applied via the nozzle at the piston. The piston is supported by the spring plate and acts against the continuously adjustable force of the compression spring. The spring plate transmits the movement of the piston onto the micro switch and
releases the latter when the set pressure is reached. This switches the electric circuit on or off, depending on the circuit set-up. The mechanical positive stop of the spring plate protects the micro switch in case of a sudden pressure drop from mechanical destruction and, in case of overpressure, prevents solid compression of the compression spring.
