A filtration system comprising: a filter manifold including: a sump; and an electronic switch assembly comprising a switch actuable between open and closed positions, the switch assembly radially disposed with respect to the sump; a filter cartridge including: a filter media; first and second end caps (34, 36) sealed to the filter media; and a body disposed between the first and second end caps and surrounding the filter media; the filtration system characterized by: a correlated magnet operably coupled to the switch assembly and comprising a plurality of magnetic field emission sources having positions and polarities relating to a predefined spatial force function that corresponds to a predetermined alignment of the plurality of magnetic field emission sources; and a complementary or paired correlated magnet radially disposed on one of the first or second end caps proximate an outside surface of the filter cartridge body; wherein the correlated magnets (40, 54) are interconnected via magnetic communication upon insertion of the filter cartridge into the sump, and upon movement of the filter cartridge into an alignment position, the correlated magnet of the filter manifold translates transversely with respect to a longitudinal axis of the sump as a result of the magnetic communication to contact an actuator to activate the switch. a filter manifold including: a sump; and an electronic switch assembly comprising a switch actuable between open and closed positions, the switch assembly radially disposed with respect to the sump; a sump; and an electronic switch assembly comprising a switch actuable between open and closed positions, the switch assembly radially disposed with respect to the sump; a filter cartridge including: a filter media; first and second end caps (34, 36) sealed to the filter media; and a body disposed between the first and second end caps and surrounding the filter media; a filter media; first and second end caps (34, 36) sealed to the filter media; and a body disposed between the first and second end caps and surrounding the filter media; the filtration system characterized by: a correlated magnet operably coupled to the switch assembly and comprising a plurality of magnetic field emission sources having positions and polarities relating to a predefined spatial force function that corresponds to a predetermined alignment of the plurality of magnetic field emission sources; and a complementary or paired correlated magnet radially disposed on one of the first or second end caps proximate an outside surface of the filter cartridge body; a correlated magnet operably coupled to the switch assembly and comprising a plurality of magnetic field emission sources having positions and polarities relating to a predefined spatial force function that corresponds to a predetermined alignment of the plurality of magnetic field emission sources; and a complementary or paired correlated magnet radially disposed on one of the first or second end caps proximate an outside surface of the filter cartridge body; wherein the correlated magnets (40, 54) are interconnected via magnetic communication upon insertion of the filter cartridge into the sump, and upon movement of the filter cartridge into an alignment position, the correlated magnet of the filter manifold translates transversely with respect to a longitudinal axis of the sump as a result of the magnetic communication to contact an actuator to activate the switch.
