Abstract
A low-travel key device includes a plate body, first and second stop sets, and a frame unit located between the first and second stop sets and including first and second frame members. The first frame member includes two first support arms each having a first end portion, and a first bight portion. The second frame member includes two second support arms each having a second end portion pivotally connected to the first end portion of a respective first support arm, and a second bight portion. A keycap is connected to the first and second bight portions, and is movable relative to the plate body between a non-depressed position, in which the first and second bight portions are away from the plate body, and a depressed position, in which the first and second bight portions are adjacent to the plate body.

A low-travel key device, comprising:
- a base plate unit including a plate body, a first stop set extending upwardly from said plate body, and a second stop set extending upwardly from said plate body and spaced apart from said first stop set in a left-right direction;
- a frame unit located between said first stop set and said second stop set and including a first frame member and a second frame member, said first frame member including two first support arms spaced apart from each other in a front-rear direction transverse to the left-right direction, and a first bight portion connected between said first support arms and adjacent to said first stop set, each of said first support arms having a first end portion, and a first arm portion connected between said first end portion and said first bight portion, said second frame member including two second support arms spaced apart from each other in the front-rear direction, and a second bight portion connected between said second support arms and adjacent to said second stop set, each of said second support arms having a second end portion pivotally connected to said first end portion of a respective one of said first support arms, and a second arm portion connected between said second end portion and said second bight portion;
- and
- a keycap connected to said first bight portion and said second bight portion such that said first bight portion and said second bight portion are rotatable relative to said keycap and such that said keycap is movable relative to said plate body between a non-depressed position and a depressed position;
- when said keycap is in said non-depressed position, said keycap, said first bight portion and said second bight portion are away from said plate body;
- when said keycap is moved from said non-depressed position to said depressed position, said first bight portion and said second bight portion respectively abut against said first stop set and said second stop set and move straight down toward said plate body;
- and
- when said keycap is in said depressed position, said keycap is adjacent to said plate body and said first bight portion and said second bight portion respectively abut against said first stop set and said second stop set and are adjacent to said plate body.
