Abstract
A multi-function control key structure formed of a key cap and a springy key body is disclosed for different triggering controls by means of a center shank of the key cap and a plurality of triggering rods of the key body around the center shank. The key cap has driving rods spaced above the triggering rods and adapted to drive the triggering rods to make a triggering action respectively. The center shank is tilted so as not to make a triggering action accidentally when the key cap is biased to force one triggering rod of the key body to make a triggering action. The driving rods do not touch the triggering rods when pressed the center area of the key cap to force the center shank to make a triggering action.
