Abstract: A cover structure, adapted for mounting on a housing that is formed with an opening and a connection base having a plugging end exposing by the opening, comprising: a frame, formed with a first end and a second end that are arranged opposite to each other with respect to the radial of a coupling position where the frame is coupled to the housing through a pivot axis of two pivot blocks in a direction parallel to a first axis direction and enabling the first end to expose by the opening; and an elastic element, disposed inside the housing for providing an elastic force to the frame, for enabling the first end and the second end to move relative to each other centering the coupling position; wherein an accommodation space is formed between the frame and the connection base so as to be used for receiving a plug of a connector.

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.
