Key switch and keyboard with the key switch

Abstract

The present application discloses a key switch and a keyboard provided with the key switch, including base, an upper cover, a button arranged between the base and the upper cover, an elastic member disposed between the lower end of the button and the base and a buffer member disposed on the outer side wall of the button, a limit structure for positioning that buff is arranged on the button, an upper end of that button passe through the upper cover and is expose to the outside of the upper cover, when the button is pushed down, the cushion contacts with the base when the button is moved to thefirst position, after the button is released, the button starts to rebound, when the button is rebounded to the second position, the cushion contacts with the upper cover, and the cushion contacts with the upper cover or the base instead of the upper and lower ends of the button, thereby avoiding collision between the button and the upper cover or the base and reducing key press sound. The limit structure can ensure the stability of the connection between the cushion and the button, prevent the cushion from being dislocated with respect to the button, effectively avoid the problem of the cushion falling off, ensure the mute effect, reduce the maintenance times, and prolong the service life of the key switch.

Description

technical field [0001] The invention relates to the technical field of keyboard equipment, in particular to a key switch and a keyboard with the key switch. Background technique [0002] The keyboard key switch is usually made of plastic material. When the key is pressed, it will touch the lower cover, and when it is popped up, it will touch the upper cover, so it is easy to make noise when it is pressed and released. In order to realize the mute of the keyboard keys, a common method is to form a buffer by adding elastic pads or gaskets under the keys, thereby reducing the sound of key presses. Adding a mute mechanism under the button can only achieve mute when the button is pressed, but after the button is bounced, it will still make a sound when it hits the top of the upper cover, and it cannot be completely muted. Some keyboards also use mute pads between the keys and the lower cover and upper cover. Since there is no limit structure between the mute pads and the keys, i...

Problems solved by technology

Adding a mute mechanism under the button can only achieve mute when the button is pressed, but after the button is bounced, it will still make a sound when it hits the top of the upper cover, and it cannot be fully muted

Some keyboards also use mute pads between the keys and the lower cover and upper cover. Since there is no limit structure between the mute pads and the keys, it is easy to loosen between the mute pads and the keys. When the keys are pressed or popped up, It is easy to cause the movement of the mute pad and the button to be out of sync, misplaced or the mute pad falls off, resulting in the failure of the mute pad
