Keyswitch structure

A keyswitch structure, comprising:

• a base having a first abutting surface substantially parallel to an X-axis direction;
• a keycap disposed above the base;
• a first support connected to and between the base and the keycap, a lower end of the first support having a rod-shaped connection portion, the rod-shaped connection portion having a first portion side surface and a second portion side surface, the first portion side surface and the second portion side surface being separated by a distance in a Y-axis direction;
• a second support movably connected to and between the base and the keycap, the keycap being supported by the first support and the second support and moving between a higher position and a lower position along a Z-axis direction through the first support and the second support, the X-axis direction, the Y-axis direction, and the Z-axis direction being non-parallel to each other;
• and
• a first connection structure disposed on the base, the first connection structure comprising:
• a first vertical-motion limiting part having a first constraining surface, the first constraining surface extending substantially along the X-axis direction, the first constraining surface and the first abutting surface defining a first engaging space therebetween, the rod-shaped connection portion being movably rotatably disposed in the first engaging space;
• and
• a first horizontal-motion limiting part having a first limiting surface, the first limiting surface being substantially perpendicular to the X-axis direction, the first limiting surface facing the rod-shaped connection portion, the first limiting surface setting a movement end of the rod-shaped connection portion along the X-axis direction by blocking the rod-shaped connection portion;
• wherein the first limiting surface and the first constraining surface are separated by the distance in the Y-axis direction;
• and
• wherein the first connection structure and the first support are arranged such that when the keycap moves relative to the base along the Z-axis direction, the first constraining surface abuts the second portion side surface without contacting the first portion side surface;, and when the keycap moves away from the base to the higher position, the first limiting surface abuts the first portion side surface without contacting the second portion side surface.

A keyswitch structure, comprising:

• a base;
• a keycap disposed above the base;
• a first support connected to and between the base and the keycap, the first support comprising a rod-shaped connection portion;
• a second support connected to and between the base and the keycap, the keycap movable between a higher position and a lower position relative to the base by movement of the first support and the second support;
• a vertical-motion limiting part, disposed on the base and engaged with the rod-shaped connection portion;
• and
• a horizontal-motion limiting part, disposed on the base and having a first limiting surface arranged to limit movement of the rod-shaped connection portion in a first direction;
• wherein the first limiting surface abuts a first portion of the rod-shaped connection portion when the keycap is in the higher position, and the horizontal-motion limiting part and the vertical-motion limiting part are both disposed on the base on a first side of the rod-shaped connection portion.
