Abstract:
1. A support member, for supporting a key cap of a keyswitch to vertically move relative to a base plate of the keyswitch, two first position structures being disposed oppositely on the base plate, the support member comprising: a first subunit, comprising a first arm, the first arm comprising a first rotation structure, a first pivoting part and a second pivoting part being bended to extend from two ends of the first arm respectively; and a second subunit, comprising a third pivoting part temporarily connected to the first pivoting part through a connection part, the connection part comprising a pre-cut portion, the connection part breaking at the pre-cut portion under a loading of an external force so that the third pivoting part and the first pivoting part are separated when the keyswitch is assembled, the second subunit further comprising a second arm and a third arm being bended to extend from two ends of the third pivoting part respectively, the second arm comprising a second rotation structure pivotally connected to the first rotation structure, wherein the second arm comprises a second position structure at an end thereof, the third arm comprises a third position structure at one end thereof corresponding to the second position structure, and a distance between the second position structure and the third position structure is longer than a distance between the two first position structures; wherein when the keyswitch is assembled, the second pivoting part and the third pivoting part are movably connected to the key cap, the third pivoting part and the first pivoting part are separated, so that the first subunit and the second subunit are able to rotate relatively around an axis of the first rotation structure and the second rotation structure, the first pivoting part is movably connected to the base plate, and the second position structure and the third position structure are movably connected to the two first position structures respectively.
