A keyswitch structure with a keycap having a balance lever is disclosed. A balance lever is pivotally installed within a keycap of a key switch. The balance lever is formed with two hooks. The balance lever is slidably matched to slots in a key seat. At least one block element (having a shape like a rib) is installed within the keycap. As the balance lever is not installed in the slots, the block element will generate a force to support and stop the balance lever so that the keycap of the key seat can not be assembled in the key seat normally and thus, it is failed in testing. Therefore, bad products can be found in the testing process. In the present invention, since a dull-proof structure is added to the balance lever of a key switch, it will prevent from unbalance due to the ineffectiveness of the balance lever as that in the prior art.
