[0006] As a further scheme of the utility model: the shell muscle is provided with four, and is arrayed on the four side walls in the inner chamber of shell.

[0007] As a further scheme of the utility model: the slider groove is provided with four, and is arrayed on the four side walls on the surface of the slider.

[0008] As a further scheme of the utility model: the V-shaped groove is provided with eight, and four groups are symmetrically arranged on both sides of the sliding block groove.

[0009] As a further scheme of the utility model: the shell rib is composed of two rectangular long strips, and the width of the outer rectangular long strip is greater than that of the inner rectangular long strip, which can be effectively clamped in the inner cavity of the sliding block groove.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The utility model discloses a sliding block increases V-shaped groove, reduces the cooperation area with the shell rib, thereby reducing the friction, improving the switch feeling, and small foreign matters can fall in the V-shaped groove and be adsorbed in grease, reducing the risk of sticking.

[0012] 2. The utility model discloses that V-shaped groove can store grease, satisfies long-term switch lubricating effect, and improves the service life of the switch.

[0013] 3. The utility model discloses that the sliding block increases V-shaped groove, and the long straight surface is changed into a small section, the size change is extremely small due to the influence of injection molding process and weather, the risk of sticking is reduced, and due to the small contact surface, the deformation points of the groove are also greatly reduced, and the risk of button sticking caused by size change is reduced.
