摘要： A key structure with a scissors-type connecting member is provided. The scissors-type connecting member includes a first frame and a second frame. The first frame has a bulge. The second frame has a recess. The height of the bulge is smaller than the length of the recess entrance. The length of the recess bottom surface is greater than the length of the recess entrance. After the bulge of the first frame is introduced into the recess of the second frame, since the length of the recess bottom surface is greater than the length of the recess entrance, the possibility of detaching the bulge from the recess during the operation of the scissors-type connecting member will be minimized.
