Abstract: A click pad which is applied to an electronic device includes a top board, a circuit board, a metal elastic board, a conductive connection layer, a bottom bracket and a restoration unit. The circuit board is located under the top board and connected to the top board. The metal elastic board under the circuit board includes a metal elastic board main body and a connection part. A buffer gap is formed between the metal elastic board main body and the circuit board. The connection part connects to the metal elastic board main body. The conductive connection layer connects to the circuit board and the connection part. The bottom bracket under the metal elastic board includes a protruding part. The protruding part supports the metal elastic board main body. The restoration unit supports the circuit board.

Abstract: A keyboard includes a base plate, a keycap, and at least one balance assembly. The base plate has a plurality of connecting structures. The keycap is above the base plate. The balance assembly includes a balance bar and two silencing members. The balance bar is between the base plate and the keycap and is engaged with the keycap. The silencing members are connected to the balance bar and engaged with the connecting structures. The balance assembly is configured to guide the keycap to move relative to the base plate. Hardnesses of the base plate and the balance bar are greater than a hardness of the silencing members.

Abstract: A key apparatus includes a substrate, a keycap, a balancing lever, and a membrane layer. The keycap is disposed on the substrate. The balancing lever is disposed between the substrate and the keycap. The balancing lever includes a shaft lever and a side lever extending from a side direction of the shaft lever. The side lever has an end away from the shaft lever. The membrane layer is disposed on the substrate. The membrane layer is provided with a cutting structure. The cutting structure is close to the end of the side lever. The membrane layer further includes a flexible limiting area located on one side of the cutting structure. The side lever of the balancing lever is inserted in the cutting structure, and makes the end be held against the flexible limiting area.
