ABSTRACT:
A keyswitch structure has a slender key cap and an integral balance structure for a key with a short press stroke. The keyswitch structure has a casing and at least one key. The casing has at least one pair of hooks arranged on a bottom face thereof, and at least one receiving groove. The key has a key cap, a connection portion parallel extended from a bottom portion of the key cap, and a balance rod integrally arranged on an end side of the connection portion. The balance rod has two sides arranged in the two hooks, respectively. The present invention can simplify the assembly steps, and efficiently prevent the key from swinging and being wedged.
