<p>An electrical harness element comprises a multi conductor cable (10) with power supply conductors (12,14,16) and a signal conductor (18). At intervals along the cable, connectors in the form of sockets (26) are fixed. The power supply conductors (12,14,16) are continuous along the length of cable, but the signal conductor (18) is interrupted at each socket by a series relay (22). The relay can be controlled by an electrical circuit (48), which is typically part of a sensor device which plugs into the socket (26). A number of the harness elements can be connected end to end as well as in branch configurations and are connected to a central computer. The relays (22) are used to assist the central computer in addressing the sensor devices. <IMAGE></p> |
