Abstract: An elevated and lower and lower keyboard apparatus comprises a base, plural of key-top-lids, plural of scissors-devices and a guiding board. The scissors-device comprises a first connection rod and a second connection rod, which are intersected to form a turning scissors configuration, which is arranged between the base and the key-top-lid.

In a movable manner, the guiding board is arranged on the base to process a movement between a first position and a second position. Relative to the plural of scissors-devices, there are plural of guiding blocks formed on the guiding board. When the guiding board moves from the second position to the first position, the guiding block presses upon the second connection rod and makes the second connection rod move closely to the base, and further, relatively to the base, it makes key-top-lid lowering down.

Abstract: An elevatable key switch and a keyboard with the elevatable key switch are provided. The elevatable key switch includes a base, a cap, an up-down mechanism, an elastic member, a movable element, and a driving element. The cap is disposed above the base. The up-down mechanism, which is disposed between the base and the cap, supports the cap to perform vertical movement relative to the base. The elastic member is disposed on the base, and the movable element is movably disposed on the elastic member. The driving element drives the movable element to make substantial horizontal movement, so that the movable element selectively moves between a first position and a second position. When the movable element is in the first position, the movable element supports the up-down mechanism in an operation configuration. When the movable element is in the second position, the movable element releases the up-down mechanism entering a contraction configuration.
