The AT42QT101x Single Key capacitive touch controller family provides an easy way to add a touch key to any application. It implements advanced filtering algorithm to offer robust operation in noisy environment. Sensitivity and low power modes can be configured as well.
The AT42QT1010 has "maximum on" touch duration of ∼ 60s.

Keys: One – configurable as either a single key or a proximity sensor
Key outline sizes: 6 mm x 6 mm or larger (panel thickness dependent), widely different sizes and shapes possible
Electrode design: Solid or ring electrode shapes
PCB Layers required: One
Electrode materials: Etched copper, silver, carbon, Indium Tin Oxide (ITO)
Panel thickness: Up to 12 mm glass, 6 mm plastic (electrode size and Cs dependent)
Key sensitivity: Settable via capacitor (Cs)
Power consumption: 17 μA at 1.8 V typical
Applications: Control panels, consumer appliances, IoT, proximity sensor applications, toys, lighting controls, mechanical switch or button replacement
