  • Depressable computer touch input device for activating an additional control signal
    Patent number: 7834858
    Abstract: A trace-detecting computer input device such as a touch input device, optical tracing module, or optical tracing plate includes a trace-detecting module and a microswitch. The trace-detecting module has a neutral position and a depressed position. A first control signal is generated when an object moves across the top of the trace-detecting module. When the trace-detecting module is in the depressed position, the microswitch is activated to generate a second control signal which is in addition to the trace-detecting first control signal.
