One embodiment of the present invention includes a method for reactively
cleaning a contact mechanism. The method includes measuring contact
resistance (CRES) associated with a plurality of electrical contacts of
the contact mechanism. The method also includes generating at least one
statistic of the measured CRES associated with the plurality of
electrical contacts of the contact mechanism, and comparing the at least
one statistic of the CRES associated with the plurality of electrical
contacts of the contact mechanism with at least one CRES threshold
parameter associated with an unacceptable level of CRES. The method
further includes cleaning the plurality of electrical contacts of the
contact mechanism based on the comparison of the at least one statistic
of the CRES and the at least one CRES threshold parameter.
