Hydraulic pressure switch with porous disc as snubbing element

A hydraulic pressure switch apparatus, said apparatus comprising;

• a porous disc directly installed at an entry port associated with a base fitting for dampening and filtration, wherein said porous disc comprises a plurality of pores connected together and to a surface of said porous disc for allowing media to flow into said base fitting;
• a piston located on a piston retainer, said piston operatively influenced by a hydraulic pressure exerted by said media, wherein said media is in turn absorbed by a compression spring;
• a plunger positioned within a housing, said plunger positionally responsive to said media flow and in communication with a micro switch,
• a switch carrier for mounting said micro switch;
• and
• a spring retainer for engaging a lower end of said compression spring and is engaged with a rod of said piston, wherein said compression spring transfers a required motion to said plunger in order to provide on/off switching capabilities based on a position of said plunger, thereby providing improved accuracy and repeatability due to a steady flow of said media and wherein said porous disc dampens pressure spikes and surges in order to significantly prolong a life of said pressure switch in harsh applications.

A method of configuring a hydraulic pressure switch apparatus, said method comprising:

• installing a porous disc directly at an entry port associated with a base fitting for dampening and filtration, wherein said porous disc comprises a plurality of pores connected together and to a surface of said porous disc for allowing media to flow into said base fitting;
• locating a piston on a piston retainer, said piston operatively influenced by a hydraulic pressure exerted by said media, wherein said media is in turn absorbed by a compression spring;
• and
• positioning a plunger within a housing, said plunger positionally responsive to said media flow and in communication with a micro switch, wherein said compression spring transfers a required motion to said plunger in order to provide on/off switching capabilities based on a position of said plunger, thereby providing improved accuracy and repeatability due to a steady flow of said media.
