The DS 307/302 is the all-rounder ("The Original")
under the series switch. By the particular
Robust construction, he is also at rough
Environmental conditions extremely reliable.
Its many variations allow
it, him for a variety of tasks in almost
to use all machines.
The pressure switch works on the piston-spring principle. If the pressure is below the set value,
the microswitch is actuated. When pressure builds up the piston works against the spring plate. This is supported
on the continuously adjustable compression spring. Upon reaching the set pressure at the nozzle,
the piston transmits the force to the spring plate whereby the microswitch is released and an electrical signal is triggered.
The pressure to be monitored is determined by the bias of the spring. The setting is successful by turning the
Adjustment element. Turning counterclockwise lowers the switching pressure. A clockwise turn increases the switching pressure.
The adjusting element is detected by the locking screw. A mechanical stop prevents the block from turning
