<p>A key lifting switch device and an assembling fixture and an assembling technology corresponding to the switch device. The key lifting switch device comprises a keycap (1) and a retractable assembly (2) which are positioned above a base plate (4), a switch mechanism (3) for closing and opening the key signal corresponding to the keycap lifting action. The retractable assembly comprises a pair of frames (23,25) which are impossible to contact with each other, are arranged in a reciprocal manner and form a cavity. The corresponding bottom edges of the two frames can be respectively arranged in two sliding kits in a sliding manner. The two sliding kits are preset at the two sides of the base plate. The respective corresponding top parts thereof are arranged in a pivoting manner with two pivoting-arranged kits. The two pivoting-arranged kits are preset on the bottom of the keycap; A synchronous sliding part (21) used for pressing the synchronous lifting of the pair of frames penetrates the cavity of the pair of the frames, one side thereof is arranged on the base plate in a pivoting manner and the other side thereof is limited to move along with the retractable movement of the bottom surface of the keycap. The invention simplifies the structure of the key lifting switch device and the assembling fixture and the assembling technology are improved, thus the production efficiency of keyboards and the finished product acceptability are further improved.</p> |
