ABSTRACT:
The present invention is an electrified bulletin board display assembly including a composite board and an illuminable push-pin for insertion therein. The board itself includes a pair of conducting layers spaced apart by an insulative layer and connected to an electrical power source. When inserted into the bulletin board, bi-terminals of the push-pin each respectively contacts one of the conductive layers. An additional layer is provided in the board to retain the push-pin in the assembly and ensure contact between the conductive layers and the bi-terminals. As constructed, the entire field of the bulletin board is capable of receiving and illuminating a number of illuminable push-pins randomly inserted therein.
