Title:
PHOTOELECTRIC MECHANICAL SWITCH, MECHANICAL KEYBOARD AND ACCELERATED EXECUTION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/107356
Kind Code:
A1
Abstract:
A photoelectric mechanical switch (100), a mechanical keyboard which applies the photoelectric mechanical switch (100) and a method for implementing accelerated execution of the photoelectric mechanical switch (100), the photoelectric mechanical switch (100) comprising a shaft core (10), a printed circuit board (PCB) (70), and at least one light transmitting element (90) and at least two light receiving elements (110) which are arranged on the PCB (70). The PCB (70) is provided with a yielding hole (701) in which the shaft core (10) is movably accommodated. The at least one light transmitting element (90) and the at least two light receiving elements (110) are arranged on two sides of the shaft core (10) in a separated manner. The shaft core (10) is provided with a plurality of through holes (101). When the shaft core (10) is pressed, the plurality of light receiving elements (110) are successively switched on or switched off. The photoelectric mechanical switch (100), by means of being provided with at least two light receiving elements (110), achieves a gradual acceleration process, thereby bringing about a gradual and coherent picture effect, thus feeling more realistic.
