Abstract

The invention discloses a metal plate touch key component. The metal plate touch key component comprises a metal plate, a mounting plate and a sensor, wherein a sensing area is arranged on the upper surface of the metal plate; the mounting plate is arranged on the lower surface of the metal plate and corresponds to the position of the sensing area; the sensor is arranged on the mounting plate; sensing electrodes with an even number are arranged on the sensor; each sensing electrode is provided with a sensing electrode lead. According to the metal plate touch key component provided by the embodiment of the invention, due to the fact that the sensing electrodes with the even number are arranged on the sensor, the number of the sensing bodies on the sensor is even and is increased, the change of sensing parameters of the sensor is more stable, and the phenomenon of a blind area can be eliminated; the sensing electrodes with the even number can sense parameter change caused by noise in the sensing area with the even number, so that the noise can be inhibited through the symmetry of parameters, a static working point is effectively stabilized, and the metal plate touch key component can be applied to a place with a more rugged environment.

Description

technical field

[0001] The present invention relates to the technical field of keys, and more particularly, to a metal plate touch key assembly. Background technique

[0002] Most of the household appliances with touch function on the market are made of materials with high insulating medium such as plastic or glass. Capacitive touch buttons can integrate the buttons and the panel, which is beautiful and elegant, and overcomes the disadvantages of gaps between the mechanical buttons, but its inherent working principle determines that the panel cannot be made of metal materials, and the product is actually In the application, due to the influence of temperature, humidity or material, there are phenomena such as unreliable buttons. Metal touch panels are not only beautiful, but also not afraid of water or harmful gases, and are not limited by materials, so they will be used more and more in home appliances.

[0003] A certain patent proposes a touch button, which uses piezoel...
