    Patent number: 6354889
    Abstract: A body plate receives a knob, retained in the body plate by a simplified terminal, to form a complete multiple-threaded terminal device. Each terminal firmly fixes into the body plate by locking into integrally formed stage portions. Each knob is retained by the snap-in terminal and preventative elements formed integrally in both the body plate and the rotating control. In a second embodiment, a body plate receives a knob and a terminal, each retained in the body plate by a rear cover, to form a complete multiple-threaded terminal device. Each rear cover firmly fixes into the body plate by locking in an integrally formed peripheral frame. Each knob is retained by the snap-in rear cover and preventative elements formed integrally with both the body plate and the rotating control.
