Abstract
A key structure comprises a baseplate, a film circuit board, an elastic body and a keycap. The film circuit board includes a deformation region and a support region. The support region is disposed on the baseplate, and a deformation space is formed between the deformation region and the baseplate. The elastic body is disposed on the film circuit board. The keycap is disposed on the elastic body.

A key structure, comprising:
- a baseplate;
- a film circuit board, including a deformation region, a support region, a lower film layer, a spacer layer, and an upper film layer, the support region is disposed on the baseplate, the spacer layer is disposed between the upper film layer and the lower film layer to form the deformation region, the lower film layer is disposed on one side of the spacer layer adjacent to the baseplate, and the upper film layer is disposed on the other side of the spacer layer away from the baseplate;
- an elastic body, disposed on a side of the film circuit board away from the baseplate;
- and
- a keycap, disposed on the elastic body,
- wherein when the keycap is pressed, the keycap presses the elastic body, and the elastic body deforms to trigger the film circuit board, the deformation region of the film circuit board deforms towards the baseplate;
- wherein the lower film layer includes a first support portion and a first deformation portion, and the upper film layer includes a second deformation portion and a second support portion, the first support portion is configured on the baseplate, and the second support portion is configured on the spacer layer, the first deformation portion is closer to the elastic body in the direction of the vertical to the baseplate in comparison with the first support portion and the second deformation portion is closer to the elastic body in the direction of the vertical to the baseplate in comparison with the second support portion to form a raised structure, and a deformation space is formed between the baseplate and the raised portion at the first deformation portion.
