| Zusammenfassung: | The utility model discloses a thin key, which comprises a substrate, a lower insulating base material, a lower circuit, an upper insulating base material, an upper switch contact, a key cap and an elastic actuating element, the substrate has a through opening. The lower circuit is formed on the lower insulating substrate and comprises at least two lower switch contacts. The upper switch contact is formed on the upper insulating substrate. The upper insulating base material is arranged on the upper surface of the substrate, and the lower insulating base material is arranged on the lower surface of the substrate, so that the upper switch contact and the at least two lower switch contacts are arranged in the through opening and are aligned with each other. The elastic actuating element is arranged between the key cap and the upper insulating base material and located above the periphery of the through opening. When the key cap is pressed to move to a pressing position, the elastic actuating element deforms to ab |
