Abstract:
1. An optical switch with positional detection, comprising in combination: an optical switch having a switch base; a key cap adjoined to a key stem having a centerline perpendicular to said switch base through the center of said key stem; said key stem is configured to move laterally to said switch base; at least one emitter and at least one detector bi-lateral to said centerline; said at least one emitter to emit an emitted beam directed to said key stem; said at least one detector to detect said directed beam; a surface on said key stem to attenuate said directed beam when lateral applied pressure is applied to said key stem; and wherein the amount of said lateral applied pressure of said key stem produces an output from said optical switch including at least said lateral applied pressure.
