As shown in fig. 3 to 7, when the whole assembly is completed, the touch switch 23 is not pressed, deformed and pressed against the pressing plate 34, the pressing plate 34 is pressed against the triggering portion 15, the upper plate unit 20 receives the elastic force provided by the touch switch 23, the upper plate unit 20 is located at a rising position, and at this time, the touch switch 23 is kept in an original state, and the touch switch 23 is not triggered by the pressing plate 34, so that no signal is generated. At this time, the positioning member 31, the ring frame member 32, the linking member 33 and the pressing plate 34 can be linked with each other by the connection between the positioning member 31 and the linking member 33, the linking member 33 and the pressing plate 34, and the connection between the linking member 33 and the ring frame member 32 through the connection ribs 35. And a moving gap for the upper plate unit 20 to descend toward the base 10 is generated between the lower side 321 and the top 11 by the protruding action of the supporting member 13 protruding from the top 11 and the bottom end 312 of the positioning member 31 protruding from the lower side 321.

As shown in fig. 3, 8 and 9, if the upper plate unit 20 is pressed by a force and corresponds to the ring frame 32, the connecting rib 35 is used to link one of the linking members 33, the linking member 33 generates flexible bias relative to the pressing plate 34, and the pressing plate 34 abuts against the trigger portion 15, so that the reaction force of the pressing plate 34 drives the touch switch 23 to be pressed to generate elastic deformation and a trigger state, so that the touch switch 23 generates a signal.

If the upper board unit 20 is pressed by a force and corresponds to one of the linkage members 33, and the linkage member 33 generates flexible bias relative to the pressing plate 34, because the pressing plate 34 abuts against the triggering portion 15, the reaction force of the pressing plate 34 drives the touch switch 23 to be pressed to generate elastic deformation and to be in a triggering state, so that the touch switch 23 generates a signal.

If the central position of the upper plate unit 20 is pressed by force and corresponds to the pressing plate 34, the touch switch 23 can be directly elastically deformed and is in a trigger state, so that the touch switch 23 generates a signal.

Therefore, even if the position of the force application point applying force to the upper plate unit 20 is different, the linking unit 30 is disposed between the base 10 and the upper plate unit 20, and the linking unit 30 utilizes the connecting rib 35 to make the ring frame 32, the linking member 33, and the pressing plate 34 linked with each other, so that when the upper plate unit 20 moves downward relative to the base 10, the touch switch 23 can elastically deform, and the purpose of accurately triggering the signal can be achieved.
