Electrical apparatus adapted to be emplaced in a support

A combination of a support and an electrical apparatus for emplacement in said support,

• said support comprising:
• a front surface arranged and adapted for insertion of said apparatus;
• a back surface;
• and
• at least one flange located adjacent to said front surface and between said front and back surfaces;
• said apparatus comprising:
• at least one securement means coacting, in an active first position, with said at least one flange of said support to hold said apparatus in said support when said apparatus is inserted into said front surface of said support;
• and
• a front surface comprising a slot in registration with said at least one securement means;
• said at least one securement means having a free end adjacent said front surface of said apparatus, said at least one securement means being movable in a direction orthogonal to said at least one flange to move said at least one securement means from said active first position to a retracted second position, wherein at least one said securement means and at least one said slot are on each of four sides of said apparatus,
• wherein said at least one securement means further comprises four angled posts each comprising two sidewalls said sidewalls extending respectively below two sides of said front surface of said apparatus, said two sides being perpendicular to each other and being disposed adjacent a corner of said front surface of said apparatus.

A combination of a support and an electrical apparatus for emplacement in said support, said support comprising:

• a first surface arranged and adapted for insertion of said apparatus;
• and
• a plurality of flanges,
• said apparatus comprising:
• a front surface having slots;
• and
• four angled posts each comprising two sidewalls, each of said sidewalls comprising a tongue, said sidewalls extending respectively below two sides of said front surface, being perpendicular to each other and being disposed adjacent a corner of said front surface;
• said slots being in registration with respective ones of said tongues;
• said tongues coacting, in an active first position, with said plurality of flanges to hold said apparatus in said support, when said apparatus is inserted into said first surface of said support;
• said tongues each having a free end adjacent to said front surface so as to be movable in a direction orthogonal to respective ones of said flanges to move said tongues from said active first position to a retracted second position.
