Abstract
A switching circuit for connecting a power source to a load is described. The circuit comprises a first relay and at least one second relay in parallel arrangement with the first relay. The switching circuit is arranged such that in the event of a fault condition occurring that requires the disconnection of the power source from the load, the at least one second relay opens while the first relay remains closed. In this manner, a reliable disconnection of the load from the switching circuit is achieved.
