The grade of 4. voltage has 6V(motorcycle) , 12V(car) , ) of 24V(derv car, go up possibly still in the car in 21 centuries the voltage grade of occurrence 42V.

5. differs according to controlling a target, its work way has instantaneous, short when and run state of 3 kinds of jobs continuously. Differ by utility its load current is OK from LmA-1000A.

6. considers dependability, car switch and other car are euqally with component in car travel process always is to be able to get the concussion of each direction force and vibration, make switch component appears inchoate attaint, riveting becomes loose etc. Additional, the car moves in still can get the influence of the harsh environment such as temperature, relative humidity, cause the oxidation aggravate of switch contact, cause switch life shorten.
