Abstract:
1. A rotating input selection device comprising: a disc-shaped rotating element having a plurality of operating projections formed on one of an end surface and a perimeter surface, wherein the plurality of operating projections are separated by circumferential intervals; a case member rotatably supporting said rotating element; a circuit substrate, disposed facing said rotating element, including fixed contact connection structures; a movable contact element opposing said fixed contact, wherein rotation of said rotating element forms a connection between said fixed contact connection structures and said movable contact; a rubber sheet formed from an insulative material disposed between said rotating element and said circuit substrate; said rubber sheet including a rubber main sheet unit and a tilting pressure section supported on said main sheet unit by a tapered cylindrical elastic support; said tilting pressure section including a tilting section, having ends, and supported on the main sheet body by said elastic support, wherein the tilting section is tiltably supported by a tilt support section projected integrally from a side of the tilting section; and an operating engagement section formed integrally with said tilting section and engaging the plurality of operating projections; wherein said contact connection structures are positioned at intervals aligned with each end of said tilting section on said circuit substrate, and wherein said rotating element is rotated to engage said operating projections with said operating engagement section, causing said tilting section supported on said circuit substrate by said tilt support section to tilt in a direction of rotation of said rotating element so that said tilting section pushes said movable contact positioned along said rotation direction toward said fixed contact.
