Claim 14:
15. N electronics box for insertion into a wall box, the electronics box comprising:
(a) a housing having a plurality of walls that define an inner volume, the plurality of walls including
(1) a top wall,
(2) a bottom wall disposed opposite to the top wall,
(3) a rear wall extending between the top wall and the bottom wall,
(4) a pair of side walls extending between the top wall and the bottom wall and adjacent to the rear wall,
(5) an intermediate wall disposed part way between the top wall and the bottom wall, and extending inward from one of the pair of side walls,
(6) a further rear wall extending between the top wall and the intermediate wall, and
(7) a further side wall extending between the top wall and the intermediate wall and adjacent to the further rear wall;

(b) wherein
(1) a given one of the plurality of walls includes
(A) an edge having at least a first part disposed along an outer surface of that wall,
(B) a curved part that curves away from the outer surface of the wall into the inner volume and forms a recess in the given one of the plurality of walls, and
(C) a tab that is disposed within the inner volume at a predetermined distance away from the outer surface of the wall and that extends from the recess along a direction parallel to the outer surface of the wall, and

(2) another one of the plurality of walls includes
(A) an edge having at least a first part disposed along an outer surface of that wall,
(B) a curved part that curves away from the outer surface of the wall into the inner volume and forms a recess in the another one of the plurality of walls,
(C) an opening formed in the recess that is completely surrounded by the recess and disposed a predetermined distance from the edge of the another one of the plurality of walls,

(3) upon the recess of the given one of the plurality of walls being brought in contact with the recess of the another one of the plurality of walls, the tab of the given one of the plurality of wall is inserted into the opening of the another one of the plurality of walls, the tab and the opening being dimensioned such that the tab securely fits into the opening and secures together the given one of the plurality of walls and the another one of the plurality of walls,
(4) the edge of the given one of the plurality of walls includes
(A) a second part of the edge that extends along the recess,
(B) a curved part disposed along the outer surface of the wall between an end of the first part and an end of the second part and that curves away from the first part such that second part is disposed lower than the first part, and
(C) the second part is disposed lower than the first part of the edge thereby forming a riser between a step formed by the first part and a step formed by the second part,

(5) the edge of the another one of the plurality of walls includes
(A) a second part of the edge that extends along the recess, and
(B) a curved part disposed along the outer surface of the wall between an end of the first part and an end of the second part and that curves away from the first part such that second part is disposed lower than the first part,
(C) the second part of the edge extends along a part of the recess at a height lower than the first part, and
(D) a third part of the edge that extends along another part of the recess at a same height as the second part and at a distance away from the second part thereby forming a riser between a step formed by the second part and a step formed by the third part, and

(6) upon the tab of the given one of the plurality of walls being inserted into the opening of the another one of the plurality of walls,
(A) the curved part of the edge of the given one of the plurality of wall presses against the curved part of the edge of the another one of the plurality of walls and further secures together the given one of the plurality of walls and the another one of the plurality of walls,
(B) the riser between the step formed by the first part and the step formed by the second part of the edge of the given one of the plurality of walls presses against the riser between the step formed by the riser between the step formed by the second part and the step formed by the third part of the edge of the another one of the plurality of walls and further secures together the given one of the plurality of walls and the another one of the plurality of walls, and
(C) upon the tab of the given one of the plurality of walls being inserted into the opening of the another one of the plurality of walls, the riser in the edge of the given one of the plurality of walls abuts the riser in the edge of the another one of the plurality of walls and further secures together the given one of the plurality of walls and the another one of the plurality of walls.
