Abstract
A keyswitch structure includes a bottom board, a circuit board disposed on the bottom board, a resilient member, a key cap and two supporting members. The bottom board is formed with two first holes spaced apart from each other. The key cap is located over the bottom board, and includes two pivoting portions that are spaced apart from each other. Each supporting member has an end pivoted to a respective one of the pivoting portions of the key cap, and an opposite end pivoted to the bottom board. When the key cap is moved toward the bottom board and presses the resilient member, each of the supporting members engages at least partly a corresponding one of the first holes, and the resilient member triggers the circuit board so as to generate a corresponding signal.
