Abstract: The present disclosure describes a housing module characterized in that it may be readily slid onto a counter-like unit which provides support therefor. The module finds particular application in the housing of electrical components, wherein the latter may be located either in a tray-like section disposed on the surface of the counter-like unit or in a box-like enclosure, below the unit. The components are electrically connected and communicate with one another via cables which are routed within the module and which may be pre-wired, thereby eliminating cable through-holes in the unit.
