Abstract:
1. A keyswitch comprising: a base; a keytop having an engaging slot, the engaging slot having a rotation space and an opening, the opening having a gap; a first support member having a first pivot shaft and a first connecting mechanism, the first pivot shaft being pivoted to the engaging slot, the first connecting mechanism being movably connected to the base, the first pivot shaft having a groove; and a second support member rotatably intersecting with the first support member and having a second connecting mechanism and a third connecting mechanism, the second connecting mechanism being movably connected to the keytop, the third connecting mechanism being movably connected to the base, the keytop being movable upward and downward relative to the base with movement of the first support member relative to the second support member; wherein when the first pivot shaft is passing through the opening of the engaging slot during the first pivot shaft is assembled into the engaging slot, the first pivot shaft is squeezed by the engaging slot to cause deformation of the groove of the first pivot shaft so as to make the first pivot shaft have a first size; when the first pivot shaft enters the rotation space via the opening, the amount of deformation of the slot decreases to make the first pivot shaft have a second size greater than the first size and the gap of the opening, so as to make the first pivot shaft constrained in the engaging slot.
