A signage display for a vehicle having a hitch receiver is provided that includes a frame defining a placard receiving area. A tongue is coupled to the frame that extends rearwardly from the frame and away from the receiving area. The tongue is adapted to be received within the hitch receiver of the vehicle. A placard is removably coupled to the frame within the placard receiving area of the frame. The signage display may thus be removably coupled to the hitch receiver of the vehicle. The vehicle owner may change the placard within the receiving area to display a variety of messages, thus alleviating the problem associated with conventional bumper stickers. In one embodiment, the frame is provided with a light socket and light that allow the placard to be illuminated.

An electrical contact for use in an electrical switching device is provided having low contact resistance, high wear resistance and high anti-weld characteristics. The contact includes a material composition of between 0.2 and 8% by weight Gr, between 10 and 90% by weight W and the remaining mixture consisting of Ag. The contact is manufactured using a process which yields a unique microstructure characterized by not having an interconnected Gr network around the Ag thereby providing a strong Ag to Ag bond. This process includes the steps of adding the appropriate amounts of Ag, W and Gr powder material together, blending together under low shear conditions to provide a homogenous powder mixture while prohibiting the Gr from smearing onto the Ag, pressing the material mixture to form a contact, and then sintering and coining the contact.
