Abstract
A keyswitch includes a cap, first and second support members slidably connected to the cap and opposite to each other, and first and second blocks formed on the cap. The cap is movable between a non-pressed position and a pressed position. The first support member abuts against the first block when the cap is located at the non-pressed position. The first block moves away from the first support member at a first gap when the cap moves downward from the non-pressed position. The first support member abuts against the cap when the cap is located at the non-pressed position, and abuts against the second block when the cap continues moving downward to the pressed position.
Claims11
A keyswitch comprising:
- a cap movable between a non-pressed position and a pressed position, a sliding slot being formed on the cap;
- a first support member having a first sliding end portion, the first sliding end portion being slidably connected to the cap to be movable along with movement of the cap;
- a second support member slidably connected to the cap, the second support member being opposite to the first support member;
- a first block formed in the sliding slot, a first concave structure extending from an outer side of the first block, the first sliding end portion having a first convex structure, the first convex structure abutting against the first block or being spaced apart from the first concave structure at a first gap when the first sliding end portion moves along with movement of the cap;
- and
- a second block formed on the cap and aligned with the first block, a second concave structure extending from the second block, the first sliding end portion further having a second convex structure, and the second convex structure abutting against the cap or the second concave structure when the first sliding end portion moves in response to the cap;
- wherein a concave slot corresponding to the first block is formed on the first support member with the first convex structure being formed in the concave slot;
- wherein the first block is configured to enter the concave slot to be spaced apart from the first convex structure when the cap is located at the pressed position.

A keyswitch comprising:
- a cap movable between a non-pressed position and a pressed position, a sliding slot being formed on the cap;
- a board disposed opposite to the cap;
- a first support member and a second support member opposite to each other and slidably connected between the cap and the board, the first support member having a first sliding end portion, the first sliding end portion being slidably connected to the cap to be movable along with movement of the cap, the first sliding end portion having a first convex structure;
- a first block formed in the sliding slot, a first concave structure extending from the first block;
- and
- a second block formed on the cap and aligned with the first block, a second concave structure extending from the second block, the first sliding end portion further having a second convex structure, and the second convex structure abutting against the cap or the second concave structure when the first sliding end portion moves in response to the cap;
- wherein when the first sliding end portion moves along with movement of the cap, the first convex structure of the first sliding end portion abuts against the first block or is spaced apart from the first concave structure;
- wherein a concave slot corresponding to the first block is formed on the first support member with the first convex structure being formed in the concave slot;
- wherein the first block is configured to enter the concave slot to be spaced apart from the first convex structure when the cap is located at the pressed position.

A keyswitch comprising:
- a cap movable between a non-pressed position and a pressed position, a sliding slot being formed on the cap;
- a first support member and a second support member slidably connected to the cap and configured opposite to each other, the first support member having a first sliding end portion slidably connected to the cap to be movable along with movement of the cap, the first sliding end portion having a first convex structure in a concave slot defined on the first support member;
- a first block and a third block formed on the cap and opposite to each other, and having a first concave structure and a third concave structure respectively defined at an outer side of each of the first block and the third block, the first block being formed in the sliding slot;
- and
- a second block formed on the cap and aligned with the first block, a second concave structure extending from the second block, the first sliding end portion further having a second convex structure, and the second convex structure abutting against the cap or the second concave structure when the first sliding end portion moves in response to the cap;
- wherein when the cap moves to the pressed position, the first concave structure of the first block is moved to face the first convex structure in the concave slot of the first support member.
