Elevatable key switch and keyboard with the same

A keyboard, comprising:

• a casing;
• at least one elevatable key switch, disposed on said casing, comprising:
• a base disposed on said casing;
• a driving element, coupled to said base and comprising a supporting portion, said supporting portion being disposed on said driving element and projecting from said base;
• a cap disposed above said base;
• an up-down mechanism, disposed between said base and said cap, configured to support said cap to perform vertical movement relative to said base;
• an elastic member disposed on said base;
• and
• a movable element movably disposed on said elastic member, configured to move responsive to movement of said supporting portion;
• wherein said movable element supports said up-down mechanism in an operation configuration when said driving element drives said movable element to substantially move to a first position, and wherein said movable element releases said up-down mechanism entering a contraction configuration when said driving element drives said movable element to substantially move to a second position.

An elevatable key switch, comprising:

• a base;
• a cap disposed above said base;
• a scissors-like structure, disposed between said base and said cap, configured to support said cap to perform vertical movement relative to said base, said scissors-like structure comprising a first arm having a first opening and a second arm having a second opening;
• an elastic member disposed on said base;
• and
• a movable element substantially horizontally movably disposed on said elastic member, said movable element comprising a receiving portion;
• wherein said receiving portion supports said scissors-like structure in an operation configuration when said movable element is in a first position, and wherein said movable element is substantially paralleledly received in said first and said second openings to release said scissors-like structure entering a contraction configuration when said movable element is in a second position.
