<p>PURPOSE:To reduce the number of wirings by arranging nonmultiple loads connected with opening/closing switches in series adjacently to a multiple unit and feed the power source to the nonmultiple loads via relays in a power distributing circuit feeding the power source to multiple loads via the multiple unit. CONSTITUTION:Acc mode signals or IG mode signals outputted from a key switch 5 are read in a multiple unit U1, and they are transmitted to another multiple unit U2a via a network NW. The multiple unit U2a controls the operations of loads (multiple loads) 6a and 6b connected to the unit U2a based on the fed mode signals. In this case, nonmultiple loads 7a, 7a and 21 are connected to the multiple unit U2a via opening/closing switches 8a, 8b and 20b. The multiple unit U2a is constituted of relays 17a-17d corresponding to the loads 7a, 7b, 6a and 6b and a controller 16 controlling these relays 17a-17d in response to the mode signals.</p> |
