Abstract

The utility model discloses a novel keyboard structure comprising a button layer, a contact layer, a light-emitting layer, a switch layer, an upper printed circuit layer and a lower printed circuit layer which are sequentially overlapped from top to bottom. Buttons and an image text which is located on the back side of the buttons are arranged in the button layer, and contact points are arranged in the contact layer. A light-emitting zone and a first through hole are arranged in the light-emitting layer, metal domes are arranged on the switch layer, a first contact zone and a second through hole are arranged in the upper printed circuit layer, and a second contact zone is arranged in the lower printed circuit layer. The different layers are overlapped to form a keyboard body conveniently and rapidly. A backlighting effect to compensate insufficient light is realized through the light-emitting layer. A UV (ultraviolet) transfer process is adopted on the right side of the button layer to produce full-sheet gapless buttons which are dustproof and waterproof. The image text which is used for identifying button names is located on the back side of the buttons and is permanently wear-resistant. The metal domes in the switch layer have short travel, low intensity and long service lives. The second through hole is capable of prolonging the travel of the metal domes, and therefore, hand feel of a user is improved.
