A system for pivotally mounting an electronic device to a wall comprising: a power connector disc having a pair of contact pads; a wall plate configured to mount to the wall having a central opening to receive the power connector disc; characterised in that the wall plate has at least one mounting slot and at least one protruding rotation limiting tab; and the system further comprises: a rotator plate configured to coaxially engage said wall plate having at least one mounting horn extending in an upward direction from the circumference and a circular central opening having at least one inwardly projecting rotation tab; a face plate configured to coaxially engage said rotator plate and said wall plate, and fixed to the wall plate to enclose the rotator plate between the wall plate and the face plate, and having a circular central opening defined by an inner circular edge and at least one strip along the said circular inner edge extending into the interior of the central opening; a back cover configured to mount to the electronic device having a pair of power contact points positioned to make contact with said pair of contact pads, at least one horn slot sized to receive to said mounting horn and at least one flap sized to receive said at least one strip; wherein said strip is positioned into said flap in a first position and said strip is positioned out of said flap in a second position; and wherein rotation of said rotator plate with respect to said wall plate and said face plate is defined by the interaction of the at least one rotation limiting tab with the at least one rotation tab. a power connector disc having a pair of contact pads; a wall plate configured to mount to the wall having a central opening to receive the power connector disc; characterised in that the wall plate has at least one mounting slot and at least one protruding rotation limiting tab; and the system further comprises: a rotator plate configured to coaxially engage said wall plate having at least one mounting horn extending in an upward direction from the circumference and a circular central opening having at least one inwardly projecting rotation tab; a face plate configured to coaxially engage said rotator plate and said wall plate, and fixed to the wall plate to enclose the rotator plate between the wall plate and the face plate, and having a circular central opening defined by an inner circular edge and at least one strip along the said circular inner edge extending into the interior of the central opening; a back cover configured to mount to the electronic device having a pair of power contact points positioned to make contact with said pair of contact pads, at least one horn slot sized to receive to said mounting horn and at least one flap sized to receive said at least one strip; wherein said strip is positioned into said flap in a first position and said strip is positioned out of said flap in a second position; and wherein rotation of said rotator plate with respect to said wall plate and said face plate is defined by the interaction of the at least one rotation limiting tab with the at least one rotation tab. a rotator plate configured to coaxially engage said wall plate having at least one mounting horn extending in an upward direction from the circumference and a circular central opening having at least one inwardly projecting rotation tab; a face plate configured to coaxially engage said rotator plate and said wall plate, and fixed to the wall plate to enclose the rotator plate between the wall plate and the face plate, and having a circular central opening defined by an inner circular edge and at least one strip along the said circular inner edge extending into the interior of the central opening; a back cover configured to mount to the electronic device having a pair of power contact points positioned to make contact with said pair of contact pads, at least one horn slot sized to receive to said mounting horn and at least one flap sized to receive said at least one strip; wherein said strip is positioned into said flap in a first position and said strip is positioned out of said flap in a second position; and wherein rotation of said rotator plate with respect to said wall plate and said face plate is defined by the interaction of the at least one rotation limiting tab with the at least one rotation tab.
