Claim 13:
14. The rotary knob switch according to claim 12, wherein the slider comprises at least one of the following various control ramps:
a self-locking ramp, a top of the self-locking ramp having a groove capable of supporting a lower edge of the control curved surface of the cam, thereby maintaining self-locking after a rotational force to the knob is released;
a self-resetting ramp, the self-resetting ramp having a bump on a top of the self-resetting ramp, and wherein a height of the self-resetting ramp is configured such that when the control curved surface of the cam reaches the top of the self-resetting ramp, the further rotation of the cam is limited by the bump on the top of the self-resetting ramp, thereby rotating reversely to reset when the rotational force to the knob is released.
