Electrical device having a base and an electrical module

An electrical device operable to communicate with another electrical device, the electrical device comprising:

• an electrical module configured to communicate between the electrical module and the another electrical device, the electrical module configured to be received by a base;
• an identification transmitter secured to and movable with respect to the base, the identification transmitter operatively coupled to the electrical module, the identification transmitter rotatably movable between a first position with respect to the electrical module in which the electrical module is in a non-operative state and a second position with respect to the electrical module in which the electrical module is in an operative state, the identification transmitter including identification information in both the first position and the second position;
• an identification pick-up which interacts with the identification transmitter in the second position in order to evaluate information defined by the identification transmitter, wherein the operative state of the electrical module is a function of the position of the identification transmitter;
• and
• wherein the information defines an address for the electrical module in order to identify the electrical module in a system.
