ABSTRACT:
A method of making a composite plastic knob including the steps of forming a plastic core having a front wall of a generally uniform thickness with an integral discernible window portion formed in a fin projecting outwardly of the front wall and with the window having a thickness less than the generally uniform thickness of the front wall; positioning an anvil in the core in supporting engagement with the window portion of the fin and injection molding an outer covering of an opaque plastic of a contrasting color over the front wall of the core except for the window portion of the fin thereof. The knob includes a plastic core having a front wall of generally uniform thickness and an integral portion of a window formed in a fin projecting outwardly of the front wall. The window is thinner than the front wall of the core. An anvil is positioned in the core in engagement with the window portion of the front wall and an outer covering of an opaque plastic overlies the front wall of the core except for the window to allow the window to function as an indicator. The anvil may be of metal and formed as part of the tooling or it may be formed of a light transmitting material which is permanently fastened into the core of the knob. The permanently fastened anvil may be equipped with radially extending hooks.
