In the case of a fault of the alarm 200, the switch 100 can be in a closed state by active triggering of a user, and the alarm 200 is powered off, i.e. the alarm stops working, and instead sends a power-on signal to the controller in a mechanical control manner, i.e. the starting of the electric vehicle is realized in a mechanical control manner.
