Modular electrical device

A modular electrical device comprising:

• a modular base comprising a plurality of base components adapted to be arranged relative to each other so as to define a backplane comprising at least one module mounting location, wherein said at least one mounting location comprises a first electrical base connector of one base component and a second electrical base connector of another base component;
• at least one removable module adapted to be respectively removably connected to said backplane in said at least one mounting location, said at least one module comprising:
• (i) a first module connector adapted to be mated with said first electrical base connector to form a mated pair of first connectors;
• and, (ii) a second module connector adapted to be mated with said second electrical base connector to form a mated pair of second connectors, wherein said module is adapted to electrically interconnect said first and second electrical base connectors of said at least one mounting location;
• a coupling device connected to said backplane and located in said at least one mounting location, said coupling device adapted to releasably secure said at least one module to said backplane.
