Meanwhile, the terms "first" and "second" in the embodiments are used only for distinguishing the description purposes, and are not intended to indicate or imply relative importance.

As shown in fig. 1-5, a key with double pressing feel for forming a switching signal in cooperation with an electronic component according to an embodiment of the present invention includes a key base 11 and a key shaft 2 installed in the key base 11 and capable of moving up and down for pressing, a key cap 1 is installed on the key shaft 2, the key base 11 is installed on a bottom plate 8, an electrical component is mounted on the bottom plate 8,

in order to realize the change of two pressing force degrees, two mutually independent first springs 3 and second springs 4 are arranged in the key seat 11, and the key shaft 2 has two strokes when moving downwards, wherein one stroke only needs to overcome the tension of the first spring 3, and the other stroke still needs to continuously overcome the tension of the second spring 4. Specifically, a top stop platform 13 having a through hole is formed in the key seat 11, and a guide groove 12 is formed at the bottom of the top stop platform 13.

Wherein, one end of the first spring 3 is propped against the top of the key shaft 2, and the other end is propped against the upper part of the propping platform 13;

the tail end of the guide post 5 is provided with a limiting bulge 13 which limits the tail end of the guide post 5 to upwards cross the top stop platform, the guide post 5 upwards passes through a through hole of the top stop platform 13 and is arranged in the first spring 3, and the extension length of the first spring 3 is greater than the length of the guide post arranged in the first spring 3 when the key shaft 2 is not subjected to external force;
