The invention discloses a keyboard switch generating a pressing sound. The keyboard switch generating the pressing sound comprises a base and a cover. The cover is arranged on the base in a covered mode to form a containing cavity, a pressing assembly, a spring and a conduction assembly are arranged in the containing cavity, the spring is located between the bottom of the pressing assembly and the base, the upper end of the pressing assembly is located at the upper end of the cover, a pressing block is arranged on the pressing assembly, a guiding slope and an elastic piece are arranged on the base respectively, one end of the elastic piece is located under the pressing block and located over the guiding slope, and the pressing block is located on the side edge of the guiding slope. According to the keyboard switch generating the pressing sound, the inner space is fully used, on the premise that a keyboard switch is small as much as possible, the keyboard switch has the good touch sense in the pressing process, the sound can be generated in the pressing process accordingly, the problem that for a long time, due to space limitation, an ultrathin keyboard switch can not generate a sound the same as that of a large keyboard switch is solved, and user experience is improved.
