PURPOSE:To prevent the rolling-in fault of material or person due to the turning left or right to a car, by providing a switch operating upon the contact of material against the side of the car for the purpose to stop the car through a brake circuit. CONSTITUTION:A switch 4 closing upon contact of material against the side of body is provided on a large-sized car such as truck. Said switch is comprised of a switching member 7 where a conductive board 6 is provided on one face of insulated stripe basebord 5 and a switching member 10 where a flexible conductive board 9 is provided on one face of elastic board 8, then they are surrounded by a elastic member 11 and mounted on the side of the car through a fixing metal 12. Then a switch 13 interlocked with a direction indicator and said switch 4 are connected in series with the brake circuit 16 to constitute the preventive device. Consequently upon contact of material against the switch 4 during the turning of the car, the brake circuit 16 functions through the switch 13 to stop the car. |
