ABSTRACT:
This invention provides apparatus for cleaning closely spaced electrical contact surfaces, such as, especially, telephone bank pins, which comprise longitudinally extending rods or wires which are closely spaced and which have exposed electrically conducting surfaces. The apparatus comprises a support means to which is attached a reciprocatably movable multi-digit cleaning member and drive means therefor. The fingers of the multi-digited member have an abrasive surface, such as a napped surface, and preferably also have means for wetting the napped surface with a cleaning liquid. The digits, or fingers, are so spaced on the member as to cooperatively interdigitate with the longitudinal electrical conducting means to be cleaned so as to abrade its surface, and thus clean, the longitudinal conducting element.
