Differentially sectioned sensing rotary disc
First Claim
1. A differentially sectioned sensing rotary disc, comprising:
- a ring body having a plurality of positioning grooves and a plurality of sensing switches on its outer circumference, wherein each of the sensing switches is provided between every two adjacent positioning grooves; and
a ring-shaped knob coaxially surrounding the ring body and formed with at least one protrusion on its inner circumference, the protrusion corresponding in position to one of the positioning grooves on the ring body such that when the knob is turned, the protrusion on the knob is moved from the corresponding positioning groove to an adjacent one of the positioning grooves and actuates the sensing switch between the two adjacent positioning grooves so as to achieve differentially sectioned actuation of the sensing switches.

Abstract
A differentially sectioned sensing rotary disc includes a ring body having a plurality of positioning grooves on its outer circumference and a knob having at least one protrusion on its inner circumference, wherein a sensing switch is provided between every two adjacent positioning grooves. The knob is ring-shaped and coaxially surrounds the ring body. The protrusion on the knob corresponds in position to one of the positioning grooves on the ring body. When the knob is turned, the protrusion on the knob turns is moved from the corresponding positioning groove to another adjacent positioning groove and actuates the sensing switch between the two adjacent positioning grooves so as to achieve differentially sectioned actuation.
