The combination lock is one opened not by a key but by the alignment of its interior parts in a definite position. The most common types have an internal mechanism consisting of a series of three or four interconnected rings or discs that are attached to and turned by a central shaft. Manually rotating the outside knob or dial turns the discs, each of which is "programmed" to stop at a notched opening or gate.
