A keyboard switch capable of being downwards pressed in a balanced manner comprises a base (1) and keycaps (2) clamped on the base. A switch terminal triggering mechanism is installed between the base and the keycaps. The switch terminal triggering mechanism is pressed by pressing a keycap, so as to allow terminals in the switch terminal triggering mechanism to be connected or disconnected to implement the function of the switch. Guide holes (11) are disposed on sides of the base, and guide columns (21) are disposed on the corresponding keycaps. The keycaps and the base are connected by means of clamping structures, or the keycaps and the switch terminal triggering mechanism are connected by means of clamping structures. In the keyboard switch, the keycaps and the base ensure the balancing and the stability of the switch by means of matching structures of the guide columns and the guide holes, and non-smooth operations caused by unbalanced force can be effectively avoided in the use; in addition, the keycaps and the base are connected by means of the clamping structures or the keycaps and the switch terminal triggering mechanism are connected by means of the clamping structures, thereby ensuring the stability of the keycaps and facilitating the disassembly and replacement. |
