Abstract
A keyswitch structure includes a base plate, a keycap, and two supports connected to the base plate and the keycap. The keycap is movable relative to the base plate through the two supports. The support is pivotally connected to the base plate through a pivotal connection structure that includes a guiding slot and a protruding shaft oppositely disposed on the support and the base plate. The guiding slot has an opening and an indentation portion. The opening is located at an upper end of the guiding slot. The protruding shaft enters the guiding slot from the opening to rotatably fit in the indentation portion, so that the support is pivotally connected to the base plate.
Claims23
A keyswitch structure, comprising:
- a base plate;
- a keycap, disposed above the base plate;
- a first support, connected to the keycap;
- and
- a first pivotal connection structure, the first support being connected to the base plate through the first pivotal connection structure, so that the first support is rotatable relative to the base plate around a first rotation axis, the first pivotal connection structure comprising:
- a first guiding slot, extending perpendicular to the first rotation axis and having a first opening and a first indentation portion, the first opening being located at an upper end of the first guiding slot, the first indentation portion being recessed parallel to the first rotation axis, the first guiding slot being disposed on one of the first support and the base plate;
- and
- a first protruding shaft, entering the first guiding slot from the first opening to rotatably fit in the first indentation portion relative to the first rotation axis, the first protruding shaft being disposed on the other of the first support and the base plate opposite to the first guiding slot.
