It can be understood that the supporting protrusion 41 on the elastic supporting member 4 abuts against the housing 6, so that the side key body 1 with the fingerprint chip and the reinforcing plate 3 can obtain a supporting force from the elastic supporting member 4, and the problems of hand feeling and inclination of the fingerprint side key 100 during use are solved; extra foam cotton does not need to be added at the two ends of the fingerprint side key 100 to provide supporting force for the fingerprint side key 100, so that the fingerprint side key 100 is balanced; this reduces the amount of material in the fingerprint side key 100, which in turn facilitates the assembly of the fingerprint side key 100 and reduces the cost of production.

Furthermore, in order to ensure that the elastic supporting member 4 can play an effective pressing role, the function of the fingerprint side key 100 for switching the key is realized; and there is a certain requirement on the structure of the elastic support member 4 in order to enable the user to obtain better force feedback when using the fingerprint side key 100. Specifically, the elastic supporting member 4 is provided with a pressing protrusion 42 on one side departing from the fingerprint FPC assembly 2, and the pressing protrusion 42 is opposite to the side key switch 5 of the fingerprint side key 100.

Preferably, the support protrusion 41 may have various shapes, such as:

in the first embodiment, as shown in fig. 3, the supporting protrusion 41 may have a circular arc shape.

In the second embodiment, as shown in fig. 4, the support protrusion 41 may have a zigzag shape.

Preferably, in order to fix the supporting protrusion 41 conveniently, the supporting protrusion 41 may further be provided with a mounting portion 43, the mounting portion 43 is configured to be embedded in the housing 6 to increase the firmness of fixing the supporting protrusion 41, and the mounting portion 43 may be configured in various forms in combination with the supporting protrusion 41, such as:

in the third embodiment, as shown in fig. 5, the support protrusion 41 has a circular arc shape and is provided with one mounting portion 43 at each of both ends.

In the fourth embodiment, as shown in fig. 6, the supporting protrusion 41 has a shape of "a few" and is provided with a mounting portion 43 at each end.
