Abstract
A key switch includes a base, a key cap, a supporting mechanism, a link bar and a buffer member. The key cap is disposed above the base. The supporting mechanism is connected to the key cap and the base to allow the key cap to move relative to the base upwardly and downwardly. The link bar includes a lower linking end. The buffer member and the base are two independent components. The buffer member is disposed on the base and made of material softer than material of the base. A restraining structure is formed on the buffer member. The lower linking end movably passes through the restraining structure. When the key cap moves relative to the base upwardly and downwardly, the lower linking end is driven to move within the restraining structure correspondingly, so as to reduce noise during movement of the lower linking end relative to the base.
