Detailed Description

The objects, technical solutions and advantages of the present utility model will become more apparent by the following detailed description of the present utility model with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and features in the embodiments may be combined with each other.

Some embodiments of the utility model are described below with reference to the accompanying drawings,

example 1:

referring to fig. 1-4, this embodiment provides a patch type soft rubber key, which includes: a body module 100.

The main body module 100 includes a base plate 110, a central column 120 mounted at the top end of the base plate 110 and extending into the base plate 110, conductive plates 130 fixed at the bottom end of the central column 120, and U-shaped hardware plates 140 symmetrically disposed and passing through the base plate 110.
