use in all oleo-hy-draulic machineries and systems as:
machine tools, presses, wooden machines, lifting apparatus, shoe, agricultural and
mobile machinery, etc.
Their opera-tion consists in changing of state of their micro-swi-tch when
the hydraulic pressure of the line on witch they are connected reaches
the set up value.
PISTON PRESSURE SWITCH Piston operated, fixed differential,
electro-hydraulic pressure switch equipped with electric contact in exchange.
When pre-set pressure is achieved, the piston actuates a microswitch. The setting adjustment is achieved by means of a grub screw (R).
