PURPOSE:To produce efficiently a molded item, by bringing a diorganopolysiloxane composition that will not crosslink into surface contact with an organopolysiloxane composition that contains a curing catalyst which can initiate the crosslinking reaction of the former composition. CONSTITUTION:A fluid organopolysiloxane that contains an electrical conductivity giving agent but does not contain a curing catalyst is cast to a part of a cavity of a mold where a contact it to be formed, and then an insulating organopolysiloxane composition that contains a curing catalyst is cast thereonto. Then the mold is heated to cure the compositions to obtain a pushing button switch cover molded body having an electrically conductive contact. |
