Abstract
A lock for an opening panel. The lock includes a rotary bolt with first and second locking notches, a strike which can be engaged in the bolt in order to lock the opening panel, a retaining pawl including at least one tooth which co-operates with the locking notches of the bolt in order to lock same in relation to the first or second locking notch, and a switch which is controlled with a control lever. The switch has two states which indicate if the lock is open or closed. In addition, the switch includes a mechanical element which co-operates with the control lever when the lock is closed, such that the switch indicates that the lock is closed only when the tooth of the retaining pawl co-operates with the second locking notch of the bolt. The mechanical element includes a pawl which maintains the control lever in position, thereby preventing the switch from changing from the first state to the second state.
