Button

Abstract

The invention provides a button. The button comprises a base plate, a button cap, an actuating piece and a magnet. A punched hole is formed in a protruding bending arm of the base plate; the button cap can move between the pressing position and the releasing position relative to the base plate; the actuating piece is provided with a bending arm part and a bearing arm part, and the bending arm part movably penetrates through the punched hole to enable the bearing arm part to be capable of vertically swinging relative to the punched hole; the magnet is fixed to one of the bearing arm part and the protruding bending arm and attracted to the other one of the bearing arm part and the protruding bending arm; when the button cap is pressed through external force to move from the releasing position to the pressing position, the bearing arm part is pressed by the button cap to be separated form the protruding bending arm; when the external force is released, the magnet generates attraction force between the bearing arm part and the protruding bending arm for attracting the bearing arm part to upwards swing to drive the button cap to move from the pressing position to the releasing position.

Description

technical field [0001] The present invention relates to a key, in particular to a key that is designed to swing up and down and abut against a key cap by using a protruding bent arm pierced through a bottom plate by an actuator so that the key cap can move up and down relative to the bottom plate. Background technique [0002] As far as the current usage habits of notebook computers are concerned, the keyboard is one of the indispensable input devices for inputting characters, symbols or numbers. Recently, due to the thinning trend of notebook computers, there is also a demand for thinner keyboards used in notebook computers. [0003] The conventional key is often provided with an elastic element, such as a rubber dome, etc., to serve as a source of elastic force for the keycap to reset when the key is used. However, the conventional elastic element has a specific height, so the key needs to have a larger space for the elastic element to be disposed therein. In other words...

AI Technical Summary

Problems solved by technology

However, the conventional elastic element has a specific height, so the button needs to have a larger space for the elastic element to be disposed therein.

In other words, because the conventional keys are provided with elastic elements, the design of the structural size of the keyboard will be limited, which is not conducive to the thinning trend of notebook computers.
