Abstract: A keyswitch device includes a circuit board, a fixing bracket, a micro switch, a keycap, and a connecting assembly. The circuit board has a first surface and a second surface opposite to the first surface. The fixing bracket includes a main body and a first hook. The main body abuts against the first surface. The first hook is connected to the main body and fixed to the circuit board. The micro switch passes through the main body, and is disposed on the circuit board and configured to generate a pressing signal to the circuit board while being pressed. The keycap is supported on the micro switch and configured to press the micro switch toward the circuit board. The connecting assembly is connected between the fixing bracket and the keycap and configured to guide the keycap to move upward and downward relative to the circuit board.

Abstract: A key structure includes a carrying body, a frame body, a keycap and at least two independent connecting members. The frame body is disposed on the carrying body and forms plurality of sliding grooves. The keycap has a plurality of cap edges and is disposed with a plurality of pivoting portions. The at least two connecting members are each connected between the keycap and the frame body, corresponding to two of the cap edges opposite to each other. Each connecting member includes a pivoting rod and a sliding rod. Each pivoting rod pivots on one of the pivoting portions, and each sliding rod is slidably limited in one of the sliding grooves. This design has preferred structural strength, smooth pressing movement and reliable pressing contact.

Abstract: A key structure includes a carrying body, a frame body, a keycap and at least two connecting members. The frame body is disposed on the carrying body, and the frame body is disposed with a plurality of sliding grooves. The keycap has a plurality of cap edges and correspondingly covers the top of the frame body, and the keycap is disposed with a plurality of pivoting portions. The at least two connecting members are independent from each other. The at least two connecting members are connected between the keycap and the frame body, corresponding to the two cap edges opposite to each other. Each connecting member includes a pivoting rod and a sliding rod. Each pivoting rod pivots on each pivoting portion. Each sliding rod is slidably limited in each sliding groove, and the pivoting portions are correspondingly located on the outside of the sliding grooves.
