Description

The improvement button

The utility model relates to button.

Patents such as the button of existing scissor structure such as notification number 237991,314250,319438,322178, its keycap is arranged on the two cross-shaped supports, keycap is moved up and down by the guiding of two supports, make the elasticity shake-up body under it press or leave wiring board, become ON or OFF action, sense of touch is preferable, can not rock, be suitable for ultra-thin keyboard, but cost height not only, cause and still have inadequately disappearance easily in the use.

The purpose of this utility model provides a kind of improvement button that uses reliable convenience, reduces cost.

The purpose of this utility model is achieved in that the improvement button, its keyseat is provided with an assembly hole, one key post is arranged at the keycap bottom, and activity is matched with in this assembly hole, it is characterized in that: this keyseat outside and keycap bottom both one of be provided with at least one and lead rib, both are provided with at least one corresponding breach, and lead rib and be matched with in the breach, therebetween and form the contact of at least one line.

Above-mentioned design makes that keycap only can be done straight to go up, the activity under straight, and can not rock, and reaches reliably effect easily of use.

Explain again with accompanying drawing, embodiment below.

Fig. 1 the utility model three-dimensional combination figure;

Fig. 2 the utility model three-dimensional exploded view;

Fig. 3 the utility model transverse sectional view;
