A C-frame formed integrally from a single piece of sheet stock has at least one of the end of the C-frame deformed over an end of the bobbin and the opposite end thereof received on the opposite end of the bobbin to increase the surface area for flux transfer to a sliding armature within the bobbin for operating a valve obturator. In one embodiment, both ends of the C-frame are each deformed respectively over one end of the bobbin.
