The invention relates to a lock comprising a housing (14, 55), a key operated lock cylinder (13, 51), which is arranged rotatable in the lock housing and a lock catch (11, 60), which is connected to the lock cylinder and rotatable between a locking position and a releasing position. The lock is arranged to be selectively set in a key operated mode, wherein the lock catch is rotatable with the lock cylinder, or in a push button operated mode, wherein the lock catch is movable by axial displacement of the lock cylinder.

1. Lock comprising: a housing,a key operated lock cylinder, which is arranged rotatable in the lock housing; anda lock catch, which is connected to the lock cylinder and rotatable between a locking position and a releasing position,wherein the lock comprises a key operated mode and a push button operated mode,such that in the key operated mode the lock catch is rotatable to the releasing position with the lock cylinder as the lock cylinder rotates about an axis, andsuch that in the push button operated mode the lock catch is movable by axial displacement of the lock cylinder axially along the axis and in relation to the lock housing;wherein the lock catch, in the push button operated mode, is rotatable to the releasing position only by and in conjunction with axial displacement of the lock cylinder. 2. Lock according to claim 1, characterized in that the lock cylinder is rotatable in a first direction, which rotation sets the lock in the key operated mode. 3. Lock according to claim 2, characterized in that the lock catch is rotated towards the releasing position by the rotation of the key in the first direction. 4. Lock according to claim 1, characterized in that the lock cylinder is rotatable in a second direction, which rotation sets the lock in the push button operated mode. 5. Lock according to claim 1, characterized in that the lock cylinder comprises a first surface which, in the key operated mode, in contact with a second surface prevents axial displacement of the lock cylinder. 6. Lock according to claim 5, characterized in that the second surface is arranged on the lock housing. 7. Lock according to claim 5, characterized in that the second surface is arranged on the lock catch. 8. Lock according to claim 1, characterized in that the lock catch is arranged rotatable in a plane at right angles to the axis of the lock cylinder. 9. Lock according to claim 1, characterized in that the lock catch is spring loaded towards the locking position. 10. Lock according to claim 1, characterized in that the lock cylinder is arranged axially slidable in an aperture in the lock catch, when in the push-button operated mode. 11. Lock according to claim 1, characterized in that at least one of the lock cylinder and the lock catch is provided with an oblique surface arranged to cooperate with a corresponding surface on the lock cylinder or the lock catch. 12. Lock according to claim 11, characterized in that the lock cylinder is provided with an oblique surface arranged to cooperate with a corresponding surface in a radially extending recess in the lock catch. 13. Lock according to claim 11, characterized in that the lock cylinder is provided with a radially extending projection arranged to cooperate with an oblique surface in a recess in the lock catch. 14. Lock according to claim 13, characterized in that the lock cylinder and the lock catch are provided with cooperating surfaces each located in a radial plane relative to the axis of the lock cylinder, which radial surfaces are arranged to prevent axial displacement of the lock cylinder. 15. A lock, comprising: a housing;a key operated lock cylinder being rotatable between a first position and a second position; anda lock catch connected to the lock cylinder, the lock catch having a lock position and a release position,wherein when the lock cylinder is in the first position, the lock operates in a key operated mode such that in response to rotation by an inserted key, the lock catch rotates to the release position with the lock cylinder about an axis; andwherein when the lock cylinder is in the second position, the lock operates in a push button operated mode such that the lock catch rotates to the release position only in response to and in conjunction with an axial movement of the lock cylinder. 16. The Lock according to claim 15 wherein rotating the key operated lock cylinder in a first direction moves the key operated lock cylinder to the first position and the lock catch is placed in the release position. 17. The Lock according to claim 16, wherein rotating the key operated lock cylinder in a second direction moves the key operated lock cylinder to the second position and the lock operates in the push button operated mode. 18. Lock comprising: a housing,a key operated lock cylinder, which is arranged rotatable in the lock housing; anda lock catch, which is connected to the lock cylinder and rotatable between a locking position and a releasing position,wherein the lock comprises a key operated mode and a push button operated mode,such that in the key operated mode, the lock catch rotates between the locking position and the releasing position only with rotation of the lock cylinder about an axis and the lock catch is not rotatable by axial displacement of the lock cylinder, andsuch that in the push button operated mode, the lock catch rotates between both the locking position and the releasing position only with and in conjunction with axial displacement of the lock cylinder, and rotation of the lock cylinder when in the push button operate mode switches the lock to the key operate mode.
