KEYSWITCH AND KEYBOARD THEREOF

摘要

A keyswitch includes a board, a cap, and a support device. The support device is disposed between the board and the cap and includes first and second support members movably connected to the cap and the board. A stopping member is formed on one of the first support member and the cap. An elastic member is formed on the other one of the first support member and the cap. When the cap is not pressed, the stopping member abuts against the elastic member to keep the cap at a non-pressed position. When the cap is pressed to a pressed position, the cap and the first support member slide relatively to make the stopping member deform the elastic member. When the cap is released, the elastic member drives the cap and the first support member to slide relatively, so as to move the cap back to the non-pressed position.

主权项

1. A keyswitch comprising:
a board; a cap; and a support device disposed between the board and the cap, the support device comprising a first support member and a second support member, the first support member and the second support member being movably connected to the cap and the board to make the cap move between a non-pressed position and a pressed position with rotation of the first support member and the second support member, a stopping member being formed on one of the first support member and the cap, an elastic member being formed on the other one of the first support member and the cap to abut against the stopping member; wherein when the cap is not pressed, the stopping member abuts against the elastic member to keep the cap at the non-pressed position; when the cap is pressed by an external force to move from the non-pressed position to the pressed position with rotation of the first support member and the second support member, the cap and the first support member slide to make the stopping member deform the elastic member; when the external force is released, the elastic member deformed by the stopping member provides an elastic force to drive the cap and the first support member to slide, so as to move the cap from the pressed position back to the non-pressed position.
