Abstract
Abstract A band selector switch comprises a rotor having click teeth on its outer circumferential surface, a sleeve rotatably fitted in the rotor and composed of a plurality of axial resilient pieces separated by axial slits defined in the sleeve, the resilient pieces having click grooves defined in inner peripheral surfaces thereof for engaging the click teeth, one of the resilient pieces being deformable radially outwardly, and stop surfaces disposed radially outwardly of those resilient pieces disposed on opposite sides of the one deformable resilient piece for preventing the resilient pieces on opposite sides of the deformable resilient piece from being deformed radially outwardly. The click teeth are prevented by the undeformable resilient pieces from entering the latter, thus limiting the range of angular movement of the rotor.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
128 words
A rotary switch comprising a fixed sleeve having a plurality of axially extending resilient pieces arranged circumferentially separated by axial slits defined in said sleeve, a rotor having click teeth on its outer circumferential surface and being rotatably fitted in said sleeve, said resilient pieces of said sleeve having click grooves defined in inner peripheral surfaces thereof for engaging said click teeth, one of said resilient pieces being deformable radially outwardly to provide a yielding click action when said rotor is moved at certain angular positions, and stop surfaces disposed radially outwardly of the other resilient pieces disposed on opposite sides of said one deformable resilient piece for preventing said other resilient pieces from being deformed radially outwardly, thereby preventing rotation of said rotor at other angular positions.
Claim 2
Dependent Claim
128 words
A rotary switch comprising a fixed sleeve having a plurality of axially extending resilient pieces arranged circumferentially separated by axial slits defined in said sleeve, a rotor having click teeth on its outer circumferential surface and being rotatably fitted in said sleeve, said resilient pieces of said sleeve having click grooves defined in inner peripheral surfaces thereof for engaging said click teeth, one of said resilient pieces being deformable radially outwardly to provide a yielding click action when said rotor is moved at certain angular positions, and stop surfaces disposed radially outwardly of the other resilient pieces disposed on opposite sides of said one deformable resilient piece for preventing said other resilient pieces from being deformed radially outwardly, thereby preventing rotation of said rotor at other angular positions.
Claim 3
Dependent Claim
36 words
A rotary switch according to claim 1, wherein said sleeve has three said resilient pieces defined by said axial slits, one of said three resilient pieces being shorter than the other two and deformable radially outwardly.
Claim 4
Dependent Claim
33 words
A rotary switch according to claim 1, wherein said deformable resilient piece has two of said click grooves, said rotor having two of said click teeth for engaging in said two click grooves.
Claim 5
Dependent Claim
33 words
A rotary switch according to claim 1, wherein said click teeth on said rotor are substantially diametrically opposite to each other, all of said resilient pieces of said sleeve having said click grooves.
Claim 6
Dependent Claim
144 words
A rotary switch comprising a fixed sleeve having a plurality of axially extending resilient pieces arranged circumferentially separated by axial slits defined in said sleeve, a rotor having click teeth and a stop projection on its outer circumferential surface and being rotatably fitted in said sleeve, said resilient pieces of said sleeve having click grooves defined in inner peripheral surfaces thereof for engaging said click teeth, one of said resilient pieces being deformable radially outwardly to provide a yielding click action when said rotor is moved at certain angular positions and having a recess defined therein, said stop projection of said rotor being disposed for free movement in said recess of said one deformable resilient piece and being engageable with side edges of the other resilient pieces on opposite sides of said recess for limiting said rotor to a certain range of angular movement.
Claim 7
Dependent Claim
144 words
A rotary switch comprising a fixed sleeve having a plurality of axially extending resilient pieces arranged circumferentially separated by axial slits defined in said sleeve, a rotor having click teeth and a stop projection on its outer circumferential surface and being rotatably fitted in said sleeve, said resilient pieces of said sleeve having click grooves defined in inner peripheral surfaces thereof for engaging said click teeth, one of said resilient pieces being deformable radially outwardly to provide a yielding click action when said rotor is moved at certain angular positions and having a recess defined therein, said stop projection of said rotor being disposed for free movement in said recess of said one deformable resilient piece and being engageable with side edges of the other resilient pieces on opposite sides of said recess for limiting said rotor to a certain range of angular movement.
Claim 8
Dependent Claim
33 words
A rotary switch according to claim 5, wherein said deformable resilient piece has two of said click grooves, said rotor having two of said click teeth for engaging in said two click grooves.
Claim 9
Dependent Claim
21 words
A rotary switch according to claim 5, wherein said stop projection has a thickness larger than that of said click teeth.
Claim 10
Dependent Claim
27 words
A switch according to claim 5 wherein said recess is formed by said one deformable resilient piece having an axial length shorter than the other resilient pieces.
