... Vss, so that it lights when the sensor is active. 2.3 AKS™ - Adjacent Key suppression The QT160 (not QT161) features adjacent key suppression for use in applications where keys are tightly spaced. If keys are very close and a large finger touches one key, the keys on either side might also activate ...
