Abstract

The invention discloses a thin photoelectric mechanical keyboard switch, comprising a PCB, a base and a keycap. A first containing slot, a second containing slot and a surrounding slot are arranged in the base. A balancing frame is arranged in the surrounding slot. A torsional spring is arranged in the first containing slot. An upper through hole is arranged in the bottom of the second containing slot. A blocking sheet, a bracket, a tension spring and a guide core are arranged in the second containing slot. One end of the tension spring is clamped in the guide core and is connected with the bracket and the other end is connected with the balancing frame. The lower end of the guide core is equipped with an insertion part. The insertion part is composed of two insertion boards which are arranged oppositely. A lower opening for clamping the tension spring is formed between the two insertion boards. Through holes are arranged in the two insertion boards. A lower through hole corresponding to the upper through hole is arranged in the PCB. A light transmitting tube and a light receiving tube are arranged on the PCB and are located on the edge of the lower through hole oppositely. The guide core slides up and down along directions of the upper through hole and the lower through hole. According to the switch, switch-on and switch-off functions are realized through light, the switch is thin, and the press balance and stability are improved.

Description

technical field [0001] The invention relates to a keyboard switch, in particular to a thin photoelectric mechanical keyboard switch. Background technique [0002] Photoelectric switch is the abbreviation of photoelectric proximity switch. It is a device that uses the object to block or reflect the light beam to change the light-receiving state of the photoelectric sensor, thereby turning on or off the circuit. Photoelectric switches are mainly used in the fields of object detection, counting, light intensity sensing and color recognition in the early stage. With the development of optoelectronic technology and the reduction of the cost of related devices, photoelectric switches have also replaced ordinary contact switches in some fields, such as replacing contact keyboard switches with photoelectric keyboard switches. [0003] Compared with ordinary contact-type keyboard switches, photoelectric keyboard switches have the advantages of fast response and long service life, bu...
