Abstract
An electrical circuit arrangement includes an unlatching actuator, a primary power source and a secondary power source. The electrical circuit arrangement further includes an operator actuated switch and an electrically controlled bypass switch having an energized condition at which the bypass switch adopts a first switching configuration and a de-energized condition at which the bypass switch adopts a second switching configuration. The circuit has a first configuration in which the bypass switch is in the first switching configuration so that the primary power source, the operator actuated switch, the bypass switch and the unlatching actuator are configured so that actuation of the operator actuated switch causes the unlatching actuator to be energized by the primary power source. The circuit has a second configuration in which the bypass switch is in the second switching configuration so that the secondary power source, the operator actuated switch, the bypass switch and the unlatching actuator are configured so that actuation of the operator actuated switch causes the unlatching actuator to be energized by the secondary power source.
