ABSTRACT:
An electrical contact is disclosed in which a contact pin having a head portion is reciprocated relative to a contact housing between upper and lower positions. The contact housing has a cylindrical portion with two oppositely opposed diagonal slots formed in the wall of the housing. A dowel pin is inserted through the slots and connected to the lower portion of the contact pin. When the contact pin is pushed to its lower position, as by placement of a corresponding contact on the contact pin, the dowel pin slides down the slots, including rotation in the contact pin about its axis. The rotation causes the contact pin head portion to be wiped against the corresponding contact, cleaning the head portion and preventing the build-up of undesirable oxides, dirt or other debris on the surface of the head portion.
