Abstract
A road vehicle electrical system includes a plurality of switches controlling remote loads. The system makes use of voltage sensitive control devices which are operated in synchronism to connect each switch to its load periodically via a conductor which is common to all the load/switch control circuits. A further common conductor conveys a control voltage signal in the form of a repeated staircase wave form to all the control devices. Analogue signal generators and detectors may also share the common conductor under the control of the same wave form generator.
