Abstract
A key structure includes a scissors-type connecting member. The scissors-type connecting member includes a first frame and a second frame. The first frame includes a first protrusion and a second protrusion. The second frame includes a first receiving recess for accommodating the first protrusion, a second receiving recess for accommodating the second protrusion, and a partition wall between the first receiving recess and the second receiving recess. When the first frame is swung with respect to the second frame, the first protrusion is sustained against a first side of the partition wall and moved on the first side of the partition wall, and the second protrusion is sustained against a second side of the partition wall and moved on the second side of the partition wall. Consequently, the first protrusion and the second protrusion are permitted to be partially detached from first receiving recess and the second receiving recess, respectively.
