FIELD: assembling and connecting modular apparatuses such as switches and the like. SUBSTANCE: electric apparatuses 3, 8, 9 such as switches are mounted on assembly rail together with associated members 4, 5. Group of apparatuses 3, 8, 9 are interconnected by electric circuit and/or are supplied with power through junction comb 12. The latter is, essentially, bus assembled of one or more current-conducting bars 14 running in parallel to each other and to longitudinal axis of rail 2 and perpendicular to one of shroud surfaces. Each of bars 14 is connected to respective phase or to neutral wire. Each contact strip of apparatuses 3, 8, 9 is electrically and selectively connected to respective current-conducting bar 14 by means of connector in the form of two blades or two grips engageable on one end with contact strips of apparatuses and on opposite end, with current-conducting bars. EFFECT: simplified design. 13 cl, 16 dwg
