Finally, bracket 20 and PCB assembly 30 may be secured together by a snap or threaded connection to assemble key assembly 200.

Referring to fig. 11, the triggering process of the key assembly 200 is as follows:

when the key 10 is pressed, the pressing force is indirectly transmitted to the switch button 31 via the silicone rubber 40, and the switch button 31 responds to a closing instruction.

In this embodiment, the rightmost key 10 in the drawing is taken as an example for schematic description, and the triggering processes of other keys 10 are similar to this and are not described in detail.

When the middle position a of the key body 11 is pressed, the pressing force is transmitted to the key boss 13 and indirectly abuts against the top end of the switch button 31 through the concave cavity, and the switch button 31 is triggered to respond to a closing instruction.

When the edge position B (or C) of the key body 11 is pressed, the pressing force is transmitted to the silicone sidewall 42 and indirectly abuts against the top end of the switch button 31 through the concave cavity, and the switch button 31 is triggered to respond to a closing instruction.

Because the surface area of the key body 11 is relatively large, when the point a in the middle of the key body 11 is pressed, the key convex column 13 is arranged in the middle of the pressing piece body 11, and the switch button 31, the pressing point a and the key convex column 13 are positioned on a same line, the switch button 31 can be triggered relatively easily to respond to a closing instruction.

When the edge position B or C of the key body 11 is pressed, the pressing force is transmitted to the switch button 31 through the silica gel 40, and the switch button 31 can be easily triggered to respond to a closing instruction, so that the hand feeling of a user when the user presses the edge position B or C is improved.

Compared with the prior art key assembly 100, because there is no silica gel 40, when the edge position B or C of the key body 11 is pressed, because the point B or C is far away from the position a of the key post 13, the pressing force acting on the point B or C is usually not enough to make the key post 13 abut against the top end of the switch button 31, so as to realize the operation of triggering the switch button 31 to respond to the closing instruction, and therefore, the user has to apply a larger pressing force to close the switch button 31, which brings a bad pressing feeling to the user.

In addition, the silica gel 40 can also enable the key 10 to be reset automatically after being pressed, so that the next operation of triggering the switch button 31 to be closed can be conveniently implemented.

Referring to fig. 12, the present invention further provides a sanitary product 300, wherein the button assembly 200 provided by the present invention is installed on a side surface of the sanitary product 300.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
