Abstract
A switch has a base comprising a flat circular recess formed on an upper surface thereof, a fixed contact disposed in an inner surface of the flat circular recess, a spring body that has a bellows shape in which a reference form unit is repetitively formed, the spring body being annularly disposed in the flat circular recess of the base, an operating body that has a turning unit fitted turnably in the flat circular recess of the base, and an operating projection provided in an inward surface of the turning unit. When the operating body is turned, the operating projection presses an end portion of the spring body to compress the spring body, which allows a contact to be switched.
Claims20
A switch comprising:
- a base comprising a flat circular recess formed on an upper surface thereof;
- a fixed contact disposed in an inner surface of the flat circular recess;
- a spring body that comprises a bellows shape in which a reference form unit is repetitively formed, the spring body being annularly disposed in the flat circular recess of the base;
- an operating body that comprises a turning unit fitted turnably in the flat circular recess of the base;
- and
- an operating projection provided in an inward surface of the turning unit,
- wherein, when the operating body is turned, the operating projection presses an end portion of the spring body to compress the spring body, which allows a contact to be switched, and
- wherein the reference form units adjacent to each other in the spring body differ from each other in a height of an apex located inside.
A switch comprising:
- a base comprising a flat circular recess formed on an upper surface thereof;
- a fixed contact disposed in an inner surface of the flat circular recess;
- a spring body that comprises a bellows shape in which a reference form unit is repetitively formed, the spring body being annularly disposed in the flat circular recess of the base;
- an operating body that comprises a turning unit fitted turnably in the flat circular recess of the base;
- and
- an operating projection provided in an inward surface of the turning unit,
- wherein, when the operating body is turned, the operating projection presses an end portion of the spring body to compress the spring body, which allows a contact to be switched, and
- wherein a leading end of an elastic arm extending from at least one outside apex is used as a movable contact in the reference form unit of the spring body.
A switch comprising:
- a base comprising a flat circular recess formed on an upper surface thereof;
- a fixed contact disposed in an inner surface of the flat circular recess;
- a spring body that comprises a bellows shape in which a reference form unit is repetitively formed, the spring body being annularly disposed in the flat circular recess of the base;
- an operating body that comprises a turning unit fitted turnably in the flat circular recess of the base;
- and
- an operating projection provided in an inward surface of the turning unit,
- wherein, when the operating body is turned, the operating projection presses an end portion of the spring body to compress the spring body, which allows a contact to be switched, and
- wherein at least an apex located inside is formed into a linear shape in the reference form units adjacent to each other in the spring body.
