Abstract
Abstract A switching device comprising a rubber switch, an operating member displaceable between at least two operative positions and a neutral position, and a cooperating member shiftable between the at least two cooperative positions and neutral position in response to displacement of the operating member. The operating member and the cooperating member are held in their neutral position due to the resilience of the rubber switch, while one contact is brought into engagement with a corresponding conductive element in the rubber switch when the corresponding member is shifted to one of the cooperative positions in response to the displacement of the operating member against the resilience of the rubber switch. The operating member includes a dial and a finger rest which in combination allows a finger of the user to be simultaneously placed on both the dial and finger rest.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
81 words
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.
Claim 2
Dependent Claim
81 words
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.
Claim 3
Dependent Claim
22 words
The operating member for a switching device according to claim 1, wherein said finger rest is integrally formed with said support structure.
Claim 4
Dependent Claim
20 words
The operating member for a switching device according to claim 1, wherein said support structure is part of a camera.
Claim 5
Dependent Claim
28 words
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.
Claim 6
Dependent Claim
27 words
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.
Claim 7
Dependent Claim
28 words
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.
Claim 8
Dependent Claim
157 words
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.
Claim 9
Dependent Claim
157 words
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.
Claim 10
Dependent Claim
22 words
