<p>An electrical supply control system from a battery to the electrical facilities of a motor vehicle is arranged to isolate the battery from the electrical facilities in some circumstances to reduce the risk of inadvertent drain on the battery. The system comprises a main switch (12) arranged to supply power from the battery (11), to the electrical facilities (15, 16). A coil (18) is arranged when energised to close the main switch (12) and is connected to be energised when an engine function element such as an ignition switch (23) is active. The coil can be disconnected from the engine function element by a connector (24). A manually operable mechanical actuator (21, 19) for the main switch is arranged in one position to close the main switch (12) to provide a continuous supply to the electrical facilities and in another position to allow the state of energisation of the coil (18) to control opening and closing of the main switch and thus isolate the loads when the engine function element i9 inactive. With battery (11), switch (12) and the connector (24) in an inaccessible locked compartment (10), the connector (24) disconnected and the main switch open mechanically, security is provided against unauthorised use of the vehicle.</p> |
