Abstract
The device controls at least one accessory which operates in an intermittent manner and is driven through a connection by the engine of the vehicle. The latter has a hydraulic steering assistance supplied with fluid under pressure through a delivery pipe by a pump which is driven by the engine through an electromagnetic clutch. A fluid pressure-switch is connected in the electric circuit of the clutch and inserted in the delivery pipe and cuts off the aforementioned connection when the delivery pressure of the pump reaches a predetermined threshold value.
