In some embodiments, when the key is mounted on the carrier 4, a side of the rib 3011 close to the carrier 4 is in contact with a side of the carrier 4 away from the pressing portion 101. Through the arrangement, after the installation of the key is completed, no gap is generated between the convex rib 3011 and the bearing piece 4, so that the waterproof function of the key is realized. In some embodiments, the initial thickness and the thickness limit deformation of the rib 3011 are greater than the maximum distance that the guide portion 102 moves toward the side of the key switch 5. Note that the initial thickness is a distance in the direction F between a side of the rib 3011 away from the carrier 4 and a side of the rib 3011 close to the carrier 4 before the rib 3011 is undeformed, and the thickness limit deformation amount is a difference between the thickness at the time of limit compression and the initial thickness. When the guide portion 102 moves to the side of the key switch 5 to the maximum distance, the side of the rib 3011 close to the carrier 4 is still in contact with the side of the carrier 4 away from the pressing portion 101. Through the arrangement, a gap is not generated between the convex rib 3011 and the bearing piece 4 all the time in the process of pressing the key, and the sealing state is kept, so that the key has a waterproof function all the time in the use process.

With continued reference to fig. 1, in some embodiments, the guide portion 102 is cylindrical, the inner diameter of the seal ring 301 is less than the diameter of the guide portion 102, and the inner diameter of the reinforcement member 302 is greater than or equal to the diameter of the guide portion 102. The seal ring 301 has elasticity. In the process of sleeving the sealing assembly 3 on the annular groove 1021 formed in the outer wall of the guide portion 102, the inner diameter of the sealing ring 301 is increased and then restored to the original size. Since the inner diameter of the seal ring 301 is smaller than the diameter of the guide portion 102, the seal ring 301 can be prevented from being detached from the outer wall of the guide portion 102. The reinforcing member 302 serves to increase the strength of the seal ring 301. Since the inner diameter of the reinforcing member 302 is larger than or equal to the diameter of the guide portion 102, the reinforcing member 302 can be smoothly sleeved on the guide portion 102 during the process of sleeving the sealing assembly 3.

In some embodiments, the inner diameter of the seal ring 301 is less than or equal to the diameter of the cross-section of the annular groove 1021 at the base of the groove. So set up, after having installed seal assembly 3, the bottom of the inner ring face of this sealing washer 301 and annular groove 1021 can produce the extrusion to can ensure that sealing washer 301 and hold and be the totally enclosed state between one side of keeping away from pressing the portion 101 of holding 4, further improve the water-proof effects of this button. It will be appreciated that when the guide portion 102 is a cylinder, the groove bottom of the annular groove 1021 is the cylindrical surface of the cylinder.

In some embodiments, the fastener 303 is a piece of fastener steel.

As shown in fig. 6, in some embodiments, the fixing member 303 forms a mounting groove 3031 having a notch, and the fixing member 303 is clamped at the bottom of the annular groove 1021 through the mounting groove 3031. It will be appreciated that the securing member 303 is captured on the bottom of the annular groove 1021. In some embodiments, the diameter of the mounting groove 3031 is smaller than the diameter of the guide portion 102, or the diameter of the mounting groove 3031 is equal to the diameter of the cross-section of the bottom cylindrical surface of the annular groove 1021. It should be noted that, in the process of being snapped into the fixing member 303, the fixing member 303 is elastically deformed, the size of the notch is increased first, when the center of the circle of the mounting groove 3031 coincides with the center of the cross section of the guide portion 102, it is considered that the assembly of the fixing member 303 is completed, and at this time, the fixing member 303 is restored to the original size. In some embodiments, the projected area of the surface of the fixing member 303 at the non-notch position in the axial direction is not smaller than the projected area of the corresponding position of the seal assembly 3 in the axial direction, so that the position of the seal assembly 3 can be better fixed.

As shown in fig. 1 and fig. 2, in some embodiments, a distance between a groove wall of the annular groove 1021 facing away from the sealing ring 301 and a groove wall of the annular groove 1021 near the sealing ring 301 is a predetermined distance, and a sum of a thickness of the sealing ring 301, a thickness of the reinforcing member 302, and a thickness of the fixing member 303 is smaller than or equal to the predetermined distance, so that the annular groove 1021 can better limit the sealing ring 301, the reinforcing member 302, and the fixing member 303.
