Referring to fig. 1 to 6, in the present embodiment, a panel button assembly is disclosed, which includes a panel 1, a PCB 2, a button member 3, and a tact switch 4, wherein the bottom of the panel 1 is provided with a plurality of connecting posts 11, the PCB 2 is connected to the bottom ends of the connecting posts 11, the panel 1 is provided with a plurality of connecting through holes 12, the PCB 2 is welded with a plurality of tact switches 4, each tact switch 4 is right under the corresponding connecting through hole 12, and the button member 3 is disposed between the connecting through hole 12 and the tact switch 4;

more specifically, the button member 3 includes a connecting seat 31, a pressing portion 32 and an elastic protruding portion 33, the elastic protruding portion 33 is connected to the top of the connecting seat 31, the pressing portion 32 is connected to the connecting seat 31, the pressing portion 32 is divided into an upper portion and a lower portion, the upper portion is above the connecting seat 31, the lower portion is below the connecting seat 31, the top end of the pressing portion 32 protrudes out of the connecting through hole 12, the bottom end of the pressing portion abuts against the top end of the tact switch 4, and the top surface of the elastic protruding portion 33 abuts against the bottom surface of the panel 1.

It should be noted that, in a normal state, that is, when the tact switch 4 is not pressed, the top end of the tact switch 4 abuts against the bottom end of the pressing portion 32, and the top surface of the elastic protruding portion 33 on the connecting seat 31 also abuts against the bottom surface of the panel 1, and the distance from the PCB 2 to the bottom surface of the panel 1 is equal to the height of the connecting column 11, because there may be the following deviations:

the tact switch 4 is welded to the PCB 2 with positive tolerance;

assembly tolerance between the PCB 2 and the connection post 11;

the above accumulated tolerance is offset by the elastic protruding part 33, in detail, the elastic protruding part 33 has a certain height stroke of automatic adjustment, the elastic protruding part 33 can be pressed and automatically rebounded relative to the connecting seat 31, when the accumulated tolerance is a positive tolerance, the placing space of the button component 3 is relatively compressed, at this time, the compression degree of the elastic protruding part 33 is larger, and the top surface of the elastic protruding part 33 is kept to be abutted against the bottom surface of the panel 1; when the accumulated tolerance is negative, the placing space of the button member 3 is relatively enlarged, and the elastic protrusion 33 is compressed to a smaller extent, and the elastic protrusion 33 keeps the top surface thereof abutting against the bottom surface of the panel 1.
