TECHNICAL FIELD
[0001] The utility model relates to a key structure, especially a key structure with good use hand feeling and touch sensing function. BACKGROUND
[0002] In a game controller, the shoulder keys of the game controller are used as operation keys with high frequency. The shoulder keys are symmetrically arranged on both sides of the front end of the game controller. The shoulder keys are usually pressed by the index finger to operate the game controller. The shoulder keys generally rebound from the original position by relying on the rebound force and the strength of their own structure. Because the shoulder keys are long, there are production tolerances and assembly tolerances between the shoulder keys and the structures of the game controller, causing a certain distance between the shoulder keys and the electronic components when the shoulder keys are pressed, resulting in a large gap between the contact points of the shoulder keys and the electronic components, and thus the shoulder keys have poor use hand feeling.
[0003] Chinese patent publication No. 108905196 discloses a game handle and its use. The game handle includes a key assembly, a switch assembly, and a key support.

The rotating shaft is buckled in the key fixing structure to make the key assembly and the key support rotatably connected.
[0004] However, the existing key assembly and switch assembly adopt zero-tolerance cooperation, which is easy to cause over-pressing. The key assembly and the key support are rotatably connected. When the key assembly is pressed, pressing a key body at different positions will require different pressing forces and will cause the key body to be skewed, affecting the use hand feeling. In addition, the existing key assembly does not have a sensing function after the finger is close.
