Description
Technical field
It is specially a kind of to press sincere slim switch without projection the present invention relates to slim switch.
Background technology
Keyboard is a kind of computer peripheral device, has multiple buttons on keyboard, and via the multiple button of pressing with defeated
Enter signal or instruction and be transferred to computer.Existing slim mechanical keyboard, such as entitled slim laptop computer mechanical keys
Disk, the Chinese patent application of Application No. 2015100926090, it discloses a kind of slim laptop computer mechanical keyboard, including
Circuit board, scissor, keycap, base, by sincere switch, spring, shell etc., added on the circuit board and reinforce iron plate, it is described
Reinforce iron plate have a transmission groove and set on multiple holding sections of edge, the scissor multiple first location divisions and
Second location division, the first location division is movably fastened in holding section up and down, and scissor is hollow, and multiple clasps are set on keycap
Portion, the holding part are snapped in second location division；When being pressed into certain stroke, feel and forth terminal act,
The sound for hitting shell upwards is produced, while when keycap is pressed, scissor keeps the balance of whole keycap, not card key,
Switch is directly installed on pcb board, and through iron plate is reinforced, the balance of keycap is kept using scissor leg structure, described to press sincere switch
Including shell, base and the sound part and contact flat spring being vertically provided in base.The slim laptop computer mechanical keyboard leads to
Cross scissor to connect keycap respectively and reinforce iron plate, keep the balance of keycap by scissor during keycap is pushed, and lead to
The sound part and contact flat spring that are vertically provided in base realize impact sound and line conduction, this kind of vertically arranged sound part and
Contact flat spring is placed in by sincere base, has following deficiency：1st, because use is larger by true and deep degree, and contact bullet
Piece is vertically arranged, and it is difficult to reduce thickness, makes the integral thickness that entirely switchs larger in the thickness plus base, does not meet existing
In the trend of slimming；2nd, the sound part of this key switch is arranged on the side of base, when the user applies pressure, by under system
Discontinuity during pressure, parts are easily damaged, and then influence the service life of key switch；3rd, contact is located at contact chip
Bottom, react slow during being pushed by system, poor sensitivity.
