摘要：An electrical contact is disclosed in which a contact pin having a head portion isreciprocated relative to a contact housing between upper and lower positions. Thecontact housing has a cylindrical portion with two oppositely opposed diagonal slotsformed 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 itslower position, as by placement of a corresponding contact on the contact pin, the dowelpin slides down the slots, including rotation in the contact pin about its axis. The rotationcauses 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 orother debris on the surface of the head portion.
