Computer mouse with dual function operating keys - used for direct control of path-pixel ratio

摘要

The computer mouse incorporates a number of operating keys which have three different switch stages for providing a dual functionality, allowing controlled variation of the path/pixel ratio during use. The path/pixel ratio for a dynamic mouse used for computer-assisted design is matched to the displacement characteristics. Each operating key can be moved from its rest position into a semi-depressed and a fully-depressed position. ADVANTAGE - Rapid, light and accurate positioning of cursor.
