[0002] At present, most elevator floor selectors adopt traditional mechanical buttons. However, with the development of high-rise elevators, for elevators with 30 to more than 100 floors, there are 30 to more than 100 buttons, which makes it very troublesome for users to find the corresponding buttons. Moreover, this kind of product has poor aesthetics, takes up a large space, and has a high installation difficulty. With the development of technology, the application scope of touch screens is becoming wider and wider. It gives a new look to human-computer interaction, with advantages such as fast response speed, space saving, and easy communication. Using this technology, users can operate the main engine by simply touching the graphics or text on the display screen with their fingers, making human-computer interaction more straightforward.

[0003] In the prior art, most touch floor selector devices are mainly installed in a wall-mounted or embedded manner. For example, in the patent publication number CN218244098U, a wall-mounted purpose floor selector terminal includes a frame assembly. A wall-mounted back panel is provided on one side of the frame assembly, and a touch glass is provided on the side of the frame assembly away from the wall-mounted back panel.
