Abstract
A pushbutton for an automotive control panel has a button portion extending through a hole in a trim plate and an enlarged skirt portion behind the plate, and is spring loaded to push the skirt against the rear surface of the plate. A ledge surrounding the button opposes the rear surface. The pushbutton is painted and paint on the ledge causes the skirt to stick to the rear surface of the plate. To prevent sticking, pointed spacers are molded on the ledge so that only the spacer points engage the plate. Sticking from paint adhesion is minimized due to the small amount of paint on the spacer points. Alternatively, the pointed spacers are formed on the rear surface of the plate.
