Electricity suction switch ordinary working principle

In fact, the principle of the electric suction function of the electric suction door is very simple, are relying on its door lock to realize, then with electric suction door lock and ordinary door lock what is the difference? First, the door lock with electric suction will be more than ordinary door locks to increase 1 motor (self-absorption motor), is used to perform electric suction action, the motor has an integrated design in the internal door locks, but also through the design of a separate mechanism to fix the motor, the motor and the door locks through the flexible cable to connect, the second of which is the more common design on the market at present; the second is that the door locks will be increased by 1 half-locking switches (or called a), this switch is a half-locking switch. The second is that the door lock will add a half-lock switch (or called a lock switch), the role of this switch is when the door is closed to the half-lock position, the switch jumps to provide a signal, the BCM (Body Controller) or DCU (Door Controller) or the door locks of their own controllers detect the half-lock switch signal jumps, then come to the self-priming motor is energized to perform the action of self-priming to the door self-priming to the full lock.
