Abstract: A method for determining contact thickness change in a contactor includes sensing a first displacement distance moved by an armature of the contactor from a reference location to a first transition point during a switch-off operation of the contactor at a first contactor life reference time when movable contacts and fixed contacts of the contactor define a first contact thickness. The method further includes sensing a second displacement distance moved by the armature from the reference location to a second transition point during a switch-off operation at a second contactor life reference time that is after the first contactor life reference time when the movable and fixed contacts define a second contact thickness that is less than the first contact thickness. The first displacement distance and the second displacement distance are used to determine a contact thickness change between the first contact thickness and the second contact thickness. A contactor adapted to implement the method is also disclosed.
