User-upgradeable load control network

A backplate, comprising:

• a backplate housing providing a cavity to removably accept any of a plurality of device control assemblies, a device control assembly of the plurality of device control assemblies including a set of device control assembly electrical contacts, the backplate housing configured to mount to an electrical junction box and further including a user interface for user control of one or more electrical loads connected to electrical wiring within the electrical junction box;
• a backplate junction box electrical connector configured to connect to the electrical wiring within the electrical junction box;
• a set of backplate electrical contacts configured to couple to the set of device control assembly electrical contacts;
• and
• a translatable cover, the cover configured to shield the set of backplate electrical contacts from the cavity when translated to a closed position, the cover further configured to expose the set of backplate electrical contacts to the device control assembly when the device control assembly is inserted into the cavity and when the translatable cover is translated to an open position, wherein the cover remains attached to the backplate housing in the open and the closed position.
