Abstract
Coding modules are connected to an electrical plug and an electrical socket to control whether or not the plug and socket can be connected to each other. Each module has a frame and two keys connected to their frames. The keys are selectively positionable on the frames to provide at least sixteen different key configurations for each module. The modules are snap-lock connected to the electrical plug and socket such that the module key configurations must be arranged in a complementary fashion before the plug and socket can be connected to each other.
