1. A swivel lever device for actuating a closure apparatus comprising one or both of a bolt closure means and a bar closure means of an access control device, wherein the access control device comprises one or both of a door and a hatch, the swivel lever device having:
a housing for fastening the swivel lever device to the access control device, and
a swivel lever for actuating the closure apparatus,
wherein the swivel lever can be adjusted relative to the housing between a latched position and an actuating position for actuating the closure apparatus (6),
wherein the swivel lever can be pivoted in the actuating position about an actuating axis relative to the housing,
wherein a locking mechanism is provided to secure the swivel lever against unauthorised adjustment from the latched position to the actuating position, and
wherein the locking mechanism comprises at least one locking element which can be adjusted between a locking position for positively blocking the swivel lever from being adjusted from the latched position to the actuating position and
an unlocking position for releasing the swivel lever for being adjusted from the latched position to the actuating position, wherein the locking element comprises at least one locking magnet for adjusting the locking element from the locking position to the unlocking position by means of the magnetic interaction between the locking magnet and at least one unlocking magnet of a corresponding key unit, wherein
the locking mechanism comprises at least two locking elements, and in that, the polarities of at least two of the locking magnets of different locking elements differ in relation to the unlocking direction of the respective locking element.
