Keyboards and other input devices are provided with membranes that extend under the keycaps or buttons. The membranes are flexible and can support conductive structures, traces, and electrical switch connections to enable effective key switches, lighting, and fluid-tightness for the keyboard. The flexible membrane is positioned near the keycaps to prevent ingress of fluids and debris into the lower portions of the key assemblies. In some cases, the flexible membrane also provides support for an interstitial layer that extends between keycaps.

The present application discloses a key structure, which includes a key cap and a connecting member. The key cap has a bottom surface, and includes a fixed part and a resilient arm. The fixed part is arranged on the bottom surface, and has a connecting hole and a first opening. The first opening is communicated with the connecting hole. At least one end of the resilient arm is connected to one side of the fixed part and is adjacent to the first opening. The resilient arm has an open end and a limiting surface. The open end is communicated with the first opening, and the limiting surface faces the bottom surface of the key cap. The connecting member includes a connecting shaft. One end of the connecting shaft is connected to the connecting member, and the other end has an extension. The connecting shaft passes through the first opening and is arranged in the connecting hole, and the extension passes through the resilient arm and is arranged between the bottom surface and the limiting surface of the key cap.
