| 20110214976 | WATERPROOF OPERATING DEVICE - A waterproof operating device has a pressure resistant housing including a support surface with one or more openings therethrough; a cover plate having corresponding openings therethrough; an elastic member having opposing major surfaces facing the support and cover plates with a protrusion extending from one major surface through an opening in the support surface. A button shaft extends through each pair of aligned openings into the protrusion. Each opposing major surface of the elastic member is maintained in direct continuous contact with the cover and support plates from the openings in the support and cover plates outward to beyond an area covered by the head portion of the button. The protrusion is dimensional for the selected elastic material and button dimensions to resist elongation from water pressure at greater than sixty meter depths, sufficient to actuate a switch element proximal to the distal end of the protrusion. | 09-08-2011 |
