Abstract: A key structure comprises a substrate, a membrane circuit disposed on the substrate, a waterproof structure disposed on the membrane circuit, a keycap, a conduction switch and a scissors structure. The waterproof structure includes a waterproof plate and a waterproof wall with a through hole. The waterproof wall surrounds the through hole and extends opposite to the membrane circuit. An end of the conduction switch passes through the through hole to be disposed on the membrane circuit, and the other end of the conduction switch protrudes from the waterproof wall to be connected to the keycap. The scissors structure includes a first end portion and a second end portion. The first end portion is pivotally connected to the keycap, and the second end portion is pivotally connected to the waterproof wall for the keycap to move up and down relatively to the membrane circuit.
