A housing for an electrical device including opposed supports or ribs receiving thereon a circuit board having first and second sides separated by a width "a". A first board support is attached to the housing and has a first side surface, a first support surface substantially perpendicular to the first side surface for supporting the circuit board, and a first recess in the first support surfac e. A second board support is attached to an opposing side surface of the housing. The side surfaces of the board supports are separated by a distance "b". When distance "a" is greater than distance "b", the circuit board is retained in an interference fit. Scrapings that are formed during the insertion of the circuit board into the housing can be collected in the support recesses, which provide relief areas, to avo id interfering with the proper seating of the circuit board on the board supports.
