Claims
- 1. An operating member for a switching device, said operating member comprising:
- (a) a support structure;
- (b) a dial being rotatably mounted for movement about an axis on said support structure, said dial including at least a portion of a generally convex quarter-spherical surface; and
- (c) a finger rest being fixedly mounted on said support structure adjacent to said dial, said finger rest including a generally convex quarter-spherical surface, said dial and said finger rest in combination forming a convex semi-spherical surface.
- 2. The operating member for a switching device according to claim 1, wherein said finger rest is integrally formed with said support structure.
- 3. The operating member for a switching device according to claim 1, wherein said support structure is part of a camera.
- 4. The operating member for a switching device according to claim 1, further comprising a cooperating member connected to said dial for actuating a switch of said switching device.
- 5. The operating member for a switching device according to claim 4, wherein said cooperating member is rotatably mounted for movement about an axis on said support structure.
- 6. The operating member for a switching device according to claim 5, wherein the axis for said dial and said axis for said cooperating member are the same axis.
- 7. An operating member for a switching device, said operating member comprising:
- (a) a support structure;
- (b) a dial projecting above said support structure and being mounted for movement about an axis on said support structure, said dial including a first substantially convex surface; and
- (c) a finger rest projecting above said support structure adjacent to said dial, said finger rest including a second substantially convex surface, said second surfaces being elongated transversely to said axis, said first surface of said dial and said second surface and said finger rest in combination together forming a substantially convex surface, said first and second surface being substantially contiguous to allow a finger of a user to be simultaneously and comfortably placed on both said dial and said finger rest, a cooperating member connected to said dial element for actuating a switch of said switching device; said cooperating member being rotatably mounted for movement about an axis on said support structure.
- 8. The operating member for a switching device according to claim 7, wherein said finger rest is integrally formed with said support structure.
- 9. The operating member for a switching device according to claim 7, wherein the axis for said dial and said axis for said cooperating member are the same axis.
- 10. The operating member for a switching device according to claim 7, wherein said support structure is part of a camera.
