Technical Field
[0001] The utility model belongs to the field of touch buttons, and in particular relates to a pressure touch button. Background Art
[0002] The pressure touch buttons in the prior art are generally capacitive sensors, which collect tiny changes in the capacitance value of the button surface through the circuit, make judgments, and finally identify the button operation; however, this type of pressure touch button is limited by its working principle. On metal or electroplated surfaces, due to its material properties, it is easy to cause the failure to identify the capacitance value change; similarly, when water, oil or other foreign matter covers the button surface, it will also cause the failure to identify the capacitance value change, resulting in button failure.

[0005] Preferably, the pressure touch button is arranged on a metal material or an electroplated material.
[0006] Preferably, the panel layer is a single-layer structure.
[0007] The utility model has the following beneficial effects: the utility model can realize pressure-sensitive touch on metal or electroplated materials, and the buttons can be operated by any object touching and pressing them; the utility model has strong anti-interference ability, and the product can realize the touch function even if it is covered with water, oil, dust, etc. The performance is not affected by the ambient temperature and humidity, and the stability is strong.
