(20 14? Yichang) As shown in the figure, before the car turns, the driver will toggle the steering crossbar, and the front and rear turn signals on the same side of the car will flash at the same time. The front and rear turn signals on the same side of the car will flash and go out at the same time, but the turn signals can work independently, so they are connected in parallel.

The driver pulls the bar before the turn signal works, so the bar acts as a switch.

So the answer is: parallel connection; Switch.
