Figure 6: Connect the bypass capacitor directly to the VCC terminal
Capacitive sensing serves as a robust alternative to traditional mechanical switches. However,
The electric field propagating from the solid-state conductive sensor to the finger is emitted from the upper surface of the sensor.
If the thickness of the covering layer is 2 millimeters or thicker,
Figure 7 shows a circular spring used for standard buttons. The manufacturing process of this circular spring button is very simple,
Due to the high lateral sensitivity of the spring, the distance between adjacent spring sensors should be as far apart as possible to avoid erroneous detection.
