The bottom layer 21 has a bottom conductive portion 211 having a pair of bottom conductive portions 211 and being pushed against The top conductive portion 221 of the bottom conductive portion 211 is contacted and electrically connected.

The pressing unit 3 is movably disposed above the circuit board unit 2 with respect to the circuit board unit 2, and the pressing unit 3 has a keycap 31 for the user to press.

The first elastic unit 4 includes a first substrate 41 located between the circuit board unit 2 and the pressing unit 3, and a flexible portion disposed between the first substrate 41 and the pressing unit 3 and disposed on the first substrate 41. The body 42 is deformed by being pushed by the pressing unit 3 and rebounds in the direction of the pressing unit 3 when the pressing unit 3 is not pushed.

The first substrate 41 has a first through hole 411. The elastic body 42 has a first elastic surrounding portion 421 surrounding the first through hole 411 and extending from the first substrate 41 toward the pressing unit 3. The first elastic surrounding portion 421 is opposite to the first pressure receiving portion 422 of one side of the first through hole 411, and is disposed in the elastic surrounding portion 421 and connected to the first pressure receiving portion 422 and is receivable by the elastic body 42. When the pressing unit 3 is pushed, the first pushing portion 423 of the second elastic unit 5 is pushed in conjunction with each other. In the embodiment, the first elastic surrounding portion 421 and the first pressure receiving portion 422 are made of elastic plastic material.

The second elastic unit 5 includes a second substrate 51 between the circuit board unit 2 and the first substrate 41, and a second substrate 51 and the elastic body 42 disposed between the second substrate 51 and the elastic body 42. The elastic member 52 of the second substrate 51 can be pushed by the elastic member 42 to pass through the second substrate 51 to push against the top layer 22 to make the top conductive portion 221 contact the bottom conductive portion 211. And rebounding in the direction of the elastic body 42 without being pushed against the elastic body 42. In the embodiment, the elastic member 52 passes through the first through hole 411 upward.

The second substrate 51 has a second through hole 511. The elastic member 52 has a base portion 521 surrounding the second through hole 511 and disposed at four angles, and is spaced apart from the base portion 521 toward the first portion. a second elastic surrounding portion 522 extending in the direction of the pushing portion 423, and a second receiving portion connecting the second elastic surrounding portion 522 opposite to the side of the second through hole 511 and spaced apart from the first pushing portion 423 The pressing portion 523 is disposed in the second elastic surrounding portion 522 and connected to the second pressure receiving portion 523, and can be driven out through the second through hole 511 when the elastic member 52 is pushed by the elastic body 52 to push A second pushing portion 524 that abuts the top layer 22 to bring the top conductive portion 221 into contact with the bottom conductive portion 211. In this embodiment, the base portion 521, the second elastic surrounding portion 522, and the second pressure receiving portion 523 are made of a metal material.

The base unit 6 is located below the circuit board unit 2.

The adapter unit 7 is disposed under the pressing unit 3 and can adjust the height through the first elastic unit 4, the second elastic unit 5 and the circuit board unit 2 to connect the base unit 6.

It should be noted that the function of the adapter unit 7 is to adjust the height of the pressing unit 3 and the base unit 6. This is not the main technical feature of the present invention, and therefore the detailed structure will not be further described in the present specification.

When the pressing unit 3 is not pressed, the first pushing portion 423 of the elastic body 42 does not contact the second pressure receiving portion 523 of the elastic member 52, and the second pushing portion of the elastic member 52 The top portion 22 does not contact the top layer 22, so the top conductive portion 221 does not contact the bottom conductive portion 211, so the top conductive portion 221 does not electrically connect with the bottom conductive portion 211.

Referring to FIGS. 3 and 5, when a user presses the pressing unit 3, the elastic force of the elastic body 42 is first overcome to interlock the first pushing portion 423 of the elastic body 42 with the first elastic member 52. The two pressure receiving portions 523, in turn, allow the user to feel the resistance of the first stage, so that during this process, the user feels the first stage of the pressing touch.

Referring to FIGS. 3 and 6, when the user continues to press the pressing unit 3 and overcomes the elastic force of the elastic member 52, the second pushing portion 524 of the elastic member 52 is pushed through the second through hole 511. When the top layer 22 contacts and electrically connects the top conductive portion 221 to the bottom conductive portion 211, the user feels the resistance of the second stage. In the process, the user feels the second stage. Press the touch.

When the user no longer presses the pressing unit 3, the pressing unit 3 receives the elastic force of the elastic member 52 and the elastic body 42 to return to the initial position.

In this way, whether or not the button is pressed can be determined based on the electrical connection state between the top conductive portion 221 and the bottom conductive portion 211.

The first elastic surrounding portion 421 and the first pressure receiving portion 422 are made of a resilient plastic material, and the second elastic surrounding portion 522 and the second pressure receiving portion 422 are made of a metal material. Therefore, during the pressing process, the touch of the first segment is softer than the touch of the second segment, and the order of the soft and hard tactile change can be provided to the user more comfortable. Press feeling.

In summary, by providing the elastic body 42 and the elastic member 52 disposed at intervals of the elastic body 42, the user can have a two-stage touch when pressed, thereby improving the comfort of the user. Therefore, the purpose of this new type can be achieved.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
