ABSTRACT:
A flat contact terminal for use in small switches is disclosed which is constructed to prevent flash, or escapement of material from a mold, when the contact terminal is insert-molded into the plastic base of the switch. The contact terminal is deformed to provide angled surfaces on the contact terminal at the upper and lower surfaces of the base where the terminal extends from the base so that the angled surfaces of the contact terminal are wedged tightly against corners of the mold, thereby preventing the escape of plastic material from the mold during molding of the base around the terminal.
