A lock comprising a lock housing, a locking bolt, and a manually actuable actuation element, wherein the actuation element is in operative connection with the locking bolt such that the locking bolt can be adjusted between an extended end position and a retracted end position by actuating the actuation element, wherein a signaling device is provided for a position detection of the locking bolt, by means of which signaling device the reaching of at least one functional position is signaled acoustically and/or haptically to a user on an adjustment of the locking bolt by an activation of the signaling device, wherein the signaling device comprises a latch device by means of which a transmission element moving along with the locking bolt can be latched to the lock housing or a component fastened thereto while emitting an acoustic and/or haptic signal, wherein the latch device comprises a spring-loaded latch element which cooperates with at least one latch recess (47, 48, 49) of the transmission element, wherein the at least one latch recess (47, 48, 49) is formed at the narrow side of the plate-shaped transmission element, namely at the narrow side of a slotted plate coupled to the locking bolt via a slotted guide, and wherein the signaling device is configured to signal at least the reaching of the extended end position and/or the retracted end position of the locking bolt, wherein the signaling device is configured to signal the reaching of the extended end position, the retracted end position and additionally at least one further, partly extended position of the locking bolt, characterized in that a guide slot formed in the slotted plate has three holding sections (40, 41, 42) which extend transversely to the adjustment direction of the locking bolt and which effect a locking of a sliding block guided in the guide slot and of the locking bolt when the locking bolt is in the retracted end position, the partly extended position or the fully extended end position. wherein a signaling device is provided for a position detection of the locking bolt, by means of which signaling device the reaching of at least one functional position is signaled acoustically and/or haptically to a user on an adjustment of the locking bolt by an activation of the signaling device, wherein the signaling device comprises a latch device by means of which a transmission element moving along with the locking bolt can be latched to the lock housing or a component fastened thereto while emitting an acoustic and/or haptic signal, wherein the latch device comprises a spring-loaded latch element which cooperates with at least one latch recess (47, 48, 49) of the transmission element, wherein the at least one latch recess (47, 48, 49) is formed at the narrow side of the plate-shaped transmission element, namely at the narrow side of a slotted plate coupled to the locking bolt via a slotted guide, and wherein the signaling device is configured to signal at least the reaching of the extended end position and/or the retracted end position of the locking bolt, wherein the signaling device is configured to signal the reaching of the extended end position, the retracted end position and additionally at least one further, partly extended position of the locking bolt, characterized in that a guide slot formed in the slotted plate has three holding sections (40, 41, 42) which extend transversely to the adjustment direction of the locking bolt and which effect a locking of a sliding block guided in the guide slot and of the locking bolt when the locking bolt is in the retracted end position, the partly extended position or the fully extended end position.
