Using Faller 161773 Car System Sensors to drive a bistable relay to schedule traffic with Faller 161675 Stop Section.
The bistable relay is a ROCO 10019. As it needs a lot of current,
I used one NPN transistor to insulate each Faller sensor from the current peaks.
The 1N4007 rectifier diode is also used to prevent reverse over voltage from the relay and protect the transistor.
