Donaldson Filter Minder Switches

A filter minder switch is the electrical part of a filter condition monitor: it closes or opens a circuit at a set restriction or differential pressure so the signal can reach a dash lamp, a telematics unit or a machine controller.

Switches are specified by their trigger point, their electrical rating and the port they thread into. Search by Donaldson part number, or give us the existing switch number and what it is wired into.
