Photoelectric key switch capable of improving pressing hand feeling

Abstract

The invention discloses a photoelectric key switch capable of improving pressing hand feeling, which comprises a balancing stand assembly, a light-emitting geminate transistor, a driving block and a key cap, and is characterized in that the balancing stand assembly comprises a base, a first balancing rod movably connected to the base, a second balancing rod movably connected to the base, and an elastic piece connected between the first balancing rod and the second balancing rod; when being pressed downwards, the first balance rod and the second balance rod respectively swing up and down in a balanced manner by taking the base as a supporting point under the elastic pulling action of the elastic piece; the light-emitting pair transistor comprises a light-emitting element and a light-sensitive element, and a light blocking piece used for blocking light between the light-emitting element and the light-sensitive element is arranged on the driving block. According to the photoelectric key switch provided by the invention, stable up-and-down swinging is realized, so that a paragraph feeling, namely a feedback feeling, is given to a human hand while the pressing balance and stability are improved, and therefore, the pressing hand feeling is increased, and the user experience is improved; meanwhile, the switch-on and switch-off actions are high in accuracy, the sensitivity of the key switch is improved, and the service life is long.

Description

technical field [0001] The invention relates to the field of key switches, in particular to a photoelectric key switch with increased pressing feel. Background technique [0002] In the existing key switch, in order to improve the pressing balance, a gimbal structure is usually added inside the key switch, so that when any position of the key cap on the key switch is pressed, it can move down smoothly, thereby improving the pressing balance. [0003] However, the existing gimbal structure only plays the role of balancing pressing, and the pressing feel is not good, which affects the user experience. [0004] At the same time, due to the limitations of the design of the internal conduction structure, the on and off actions have low accuracy and low sensitivity. SUMMARY OF THE INVENTION [0005] In view of the above deficiencies, the purpose of the present invention is to provide a photoelectric key switch with an increased pressing feel, so as to achieve a smooth up and do...
