Abstract
A deadlock prevention device of a keyswitch key includes a keycap and a base between which a scissors-like linkage mechanism is deformably received. The scissors-like linkage mechanism has a slidable and rotatable member formed at an intermediate portion thereof for deformation in response to a depression on the keycap. Therefore, the deadlock prevention device of the keyswitch key prevents the keyswitch key from deadlocking during operation.
