Abstract
Abstract A rotary elastic component with a push switch comprises a bearing having a through hole and a collar portion provided at the end to close a part of the through hole, a rotary electrical component having a rotating body with a hole, a push switch disposed at the rear of the rotary electrical component and having a moving contact and a stationary contact, and an operating shaft inserted into the through hole of the bearing and the hole of the rotating body and having a collar portion. The collar portion of the operating shaft is positioned within the through hole of the bearing, to thereby retain, by the collar portion of the bearing, the operating shaft from accidentally loosening from position. When the operating shaft is rotating, the rotating body is rotated to operate the rotary electrical component; the operating shaft being axially moved to actuate the push switch. Furthermore, an elastic member is mounted, within the through hole of the bearing, between the collar portion of the bearing and the collar portion of the operating shaft.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
220 words
A rotary electrical component with push switch, comprising: a bearing having a through hole and a collar portion provided at a front end to close a part of said through hole; a rotary electrical component having a rotating body with a hole; a push switch disposed at a side of said rotary electrical component opposite rotating body and having a moving contact and a stationary contact; and an operating shaft inserted into said through hole of said bearing and said hole of said rotating body having a collar portion, wherein said collar portion of said operating shaft is positioned within said through hole of said bearing, to thereby retain, by said through hole of said bearing, to thereby retain, by said collar portion of said bearing, said operating shaft from accidentally loosening from position; with said operating shaft rotating, said rotating body is rotated to operate said rotary electrical component; said operating shaft is axially moved to actuate said push switch; and an elastic member mounted between said collar portion of said bearing and said collar portion of said operating shaft within said through hole of said bearing, wherein said elastic member exerts a force on said collar portion of said bearing and said collar portion of said operating shaft when said operating shaft is not subject to axial movement.
Claim 2
Dependent Claim
220 words
A rotary electrical component with push switch, comprising: a bearing having a through hole and a collar portion provided at a front end to close a part of said through hole; a rotary electrical component having a rotating body with a hole; a push switch disposed at a side of said rotary electrical component opposite rotating body and having a moving contact and a stationary contact; and an operating shaft inserted into said through hole of said bearing and said hole of said rotating body having a collar portion, wherein said collar portion of said operating shaft is positioned within said through hole of said bearing, to thereby retain, by said through hole of said bearing, to thereby retain, by said collar portion of said bearing, said operating shaft from accidentally loosening from position; with said operating shaft rotating, said rotating body is rotated to operate said rotary electrical component; said operating shaft is axially moved to actuate said push switch; and an elastic member mounted between said collar portion of said bearing and said collar portion of said operating shaft within said through hole of said bearing, wherein said elastic member exerts a force on said collar portion of said bearing and said collar portion of said operating shaft when said operating shaft is not subject to axial movement.
Claim 3
Dependent Claim
91 words
A rotary electrical component with push switch according to claim 1, wherein a projection is provided on at least either said collar portion of said bearing or said collar portion of said operating shaft, on a side where said collar portion of said bearing and said collar portion of said operating shaft face each other, to provide a smaller gap between said projection and said collar portion than a gap between said collar portion of said bearing and said collar portion of said operating shaft where said elastic member is interposed.
Claim 4
Dependent Claim
200 words
A rotary electrical component with push switch comprising: a bearing having a through hole and a collar portion provided at a front end to close a part of said through hole; a rotary electrical component having a rotating body with a hole; a push switch disposed at a side of said rotary electrical component opposite rotating body and having a moving contact and a stationary contact; and an operating shaft inserted into said through hole of said bearing and said hole of said rotating body having a collar portion, wherein said collar portion of said operating shaft is positioned within said through hole of said bearing, to thereby retain, by said through hole of said bearing, to thereby retain, by said collar portion of said bearing, said operating shaft from accidentally loosening from position; with said operating shaft rotating, said rotating body is rotated to operate said rotary electrical component; said operating shaft is axially moved to actuate said push switch; and a curved elastic member mounted between said collar portion of said bearing and said collar portion of said operating shaft within said through hole of said bearing, wherein said elastic member is formed of a curved metal plate.
Claim 5
Dependent Claim
200 words
A rotary electrical component with push switch comprising: a bearing having a through hole and a collar portion provided at a front end to close a part of said through hole; a rotary electrical component having a rotating body with a hole; a push switch disposed at a side of said rotary electrical component opposite rotating body and having a moving contact and a stationary contact; and an operating shaft inserted into said through hole of said bearing and said hole of said rotating body having a collar portion, wherein said collar portion of said operating shaft is positioned within said through hole of said bearing, to thereby retain, by said through hole of said bearing, to thereby retain, by said collar portion of said bearing, said operating shaft from accidentally loosening from position; with said operating shaft rotating, said rotating body is rotated to operate said rotary electrical component; said operating shaft is axially moved to actuate said push switch; and a curved elastic member mounted between said collar portion of said bearing and said collar portion of said operating shaft within said through hole of said bearing, wherein said elastic member is formed of a curved metal plate.
