The invention relates to a lock having a locking mechanism comprising a rotary latch and a pawl for locking the rotary latch in a locked position of the lock. An identification device for identifying a position of a moving component of the lock is provided. The identification device comprises a spring which is fitted to the component. The spring opens or closes an electrical circuit when the component and the spring which is connected to said component are moved. In this way, positions of the locking mechanism can be reliably determined, without having to worry about fatigue of the spring and associated problems.
