Abstract
A key structure includes a base plate, a position-limiting structure, a stabilizer bar and a keycap. The position-limiting structure is connected with and fixed on the base plate. A slot is defined by the position-limiting structure and the base plate. The stabilizer bar is connected with the keycap and pivotally coupled to the slot. The position-limiting structure includes a top stopper. The top stopper is made of soft material. As the stabilizer bar is rotated and the stabilizer bar is contacted with the top stopper, the efficacy of reducing noise is enhanced.
Claims9
A key structure, comprising:
- a base plate;
- a membrane circuit board located over the base plate;
- at least one position-limiting structure comprising a top stopper and a sidewall, wherein the top stopper and the sidewall are connected with each other, the sidewall is penetrated through the membrane circuit board and connected with and fixed on the base plate, a slot is defined by the top stopper, the sidewall and the base plate collaboratively, and a material hardness of the top stopper is lower than a material hardness of the sidewall;
- at least one stabilizer bar comprising a main bar part and at least one lateral bar part, wherein the main bar part and the at least one lateral bar part are connected with each other, and a distal end of the lateral bar part is pivotally coupled to the slot, wherein the top stopper is contacted with the distal end of the lateral bar part in response to rotation of the stabilizer bar;
- and
- a keycap, wherein the main bar part is pivotally coupled to a bottom surface of the keycap.
