Claim:
1. A keyboard equipped with multipoint press positions, comprising at least a baseboard, a keycap assembly and a command trigger assembly triggered by the keycap assembly to output keyboard commands, the keycap assembly including a support frame and a plurality of keycaps located on the support frame, the command trigger assembly including: a command circuit board which includes a plurality of trigger portions corresponding to press positions of the keycaps and triggered by the keycaps to output a plurality of keyboard commands and at least one primary command circuit electrically connected to each trigger portion, each trigger portion including at least one primary trigger switch corresponding to a central position of each keycap and at least two secondary trigger switches spaced from the primary trigger switch at a preset distance, each secondary trigger switch including a first auxiliary trigger switch and a second auxiliary trigger switch opposing each other relative to the primary trigger switch, the primary trigger switch and the secondary trigger switches being interposed by at least one secondary command circuit to form electrical connection thereof, wherein the at least one of the primary command circuit of the trigger portions is triggered by the primary trigger switch and out puts one of the keyboard commands, wherein each of the at least one secondary command circuit of the trigger portions corresponding to the primary command circuit is triggered by the secondary trigger switches and generates the same keyboard command as the primary command circuit outputs; and a plurality of elastic switches corresponding to the press positions of the keycaps and depressible by the keycaps to trigger the trigger portions to output the keyboard commands, each elastic switch including a base, a primary movement portion located on the base and corresponding to the primary trigger switch, a first secondary movement portion located on the base and corresponding to the first auxiliary trigger switch and a second secondary movement portion located on the base and corresponding to the second auxiliary trigger switch, wherein the primary movement portion includes a primary movement strut depressible by the keycap to move towards the command circuit board to trigger the primary truer switch and a primary deformation section connected to the primary movement strut to provide a return force to the primary movement strut, the first secondary movement portion including a first secondary movement strut depressible by the keycap to move towards the command circuit board to trigger the first auxiliary trigger switch and a first secondary deformation section connected to the first secondary movement strut to provide a return force to the first secondary movement strut, the second secondary movement portion including a second secondary movement strut depressible by the keycap to move towards the command circuit board to trigger the second auxiliary trigger switch and a second secondary deformation section connected to the second secondary movement strut to provide a return force to the second secondary movement strut, and wherein the first secondary movement strut includes a first press plane facing the keycap and a first press sloped surface connected to the first press plane and located at one side of the first secondary movement strut remote from the primary movement strut, and the second secondary movement strut includes a second press plane facing the keycap and a second press sloped surface connected to the second press plane and located at one side of the second secondary movement strut remote from the primary movement strut.
