The bistables inside CMOS 4013 are conected in series. FF2 is configured as a R-S memory to store the state of the switch.
How does a car know if the door is open?
Each sensor system consists of a way to signal whether the electrical circuit is opened or closed, depending on the function of the signal. Car door sensors are part of this same system. There is a wire that runs from the box to different parts of your car, depending on what your vehicle is designed to signal.
