Abstract
A manual timer switching device has a housing, a program carrier, and a manually rotatable knob. The housing contains a timer switch. The program carrier is rotatably mounted to a front side of the housing, concentric with the housing. The knob is seated coaxially with the program carrier and is rotatable relative to the program carrier to manually control the timer switch via a mechanical connection. The knob has a single ended, bar-shaped operating handle on a front face thereof. The program carrier has a central opening through which the operating handle is seated. The rotating knob can also have a radially extending surface finish or markings near its peripheral circumferential region.
