t is described herein a devise advising the driver that the adhesion of its vehicle on the road runs the risk of being lost due to the centrifugal force exerted when the vehicle is moving in a curvilinear trajectory. The device can be regulated according to the sensitivity of response regarding the changeable external operational conditions, the driver's desire, the driving habilities thereof and the car's performance. The centrifugal force becomes perceptible via adequate arrangement and combination of previously-graduated mercury switches showing high reliability and constant behaviour all through the function time; the mercury bulb isolated from the environment is oscillating into the cylindrical catridge of same switches so that nomaintenance thereof is required. For the graduation of the mercury switches, it is proposed the use of the adequate respective graduating device accompanying the invented one. |
