A switch device includes a moving unit, a manual unit, a plurality of securing members and an actuating mechanism. The moving unit includes a ring gear, first and second sliding members, and a first connecting member. The first and second sliding members are slidable relative to the ring gear and respectively in mutually perpendicular directions. The securing members extend through the first connecting member and the first sliding member into the manual unit for securing the first sliding member between the first connecting member and the manual unit. The actuating mechanism is co-movably connected to the second sliding member and is adapted for actuating operation of a lock mechanism.

An electrical connector assembly includes a housing, a connector rotating unit and a second magnetic attraction element. The connector rotating unit is rotatable relative to the housing under action of an external force. The connector rotating unit includes a rotating body, a first magnetic attraction element fixed to the rotating body, and an electrical connector fixedly connected to the rotating body. The second magnetic attraction element is disposed in the housing. The second magnetic attraction element is configured to attract the first magnetic attraction element to rotate the connector rotating unit automatically back to an original position after the connector rotating unit is rotated and the external force is released.

A circuit board connection structure includes an adapter circuit board and an interface circuit board. The upper board face of the adapter circuit board is provided with a connection via, and an arcuate adapter pad coaxial with the connection via. A conductive pin is secured to the arcuate adapter pad. The conductive pin is provided with a protrusion. The lower board face of the interface circuit board is provided with a rotation shaft, and an arcuate interface pad coaxial with the rotation shaft. The rotation shaft is inserted into the connection via. The interface circuit board is configured to swing relative to the adapter circuit board about the axis of the rotation shaft. The protrusion is pressed against the arcuate interface pad and is configured to slide relative to the arcuate interface pad.

A known quick connect electrical connector has plug which has a spindle through which a rod is passed. Metal balls are contained within the spindle and can be pushed radially outwardly by a widened portion of the rod to lock the spindle to a passage in a corresponding socket. To separate the plug and socket, the rod must be pushed to move the widened portion away from the balls. To accomplish this, a cam follower is attached to the rod. Slide supports are attached to the plug. A lever slides within the slide supports and has a cam surface which pushes the cam follower when the lever is slid within the slide supports. When the cam follower is pushed, it moves the rod to enable the metal balls to move radially inwards to release the plug from the socket.

The present invention relates to a concealable apparatus assembly, comprising a support structure (5) supporting an apparatus (M) and rotatably receivable in an opening (1a) of a board or of a plate (1) so that the apparatus (M) is accessible through said opening (1a) from a first major surface of the board or plate (1) at a first angular position adopted by said support structure (5), and concealed for other angular positions adopted thereby, the support structure (5) having or supporting a flat surface (2) which remains flush with said first major surface of the board or plate (1) at a second angular position adopted by said support structure (5). The support structure (5) is also linearly receivable in said opening (1a) so that it can move linearly according to an approaching/distancing direction with respect to the board or plate (1).
