• the subject of the invention is an electrical control device for locking / unlocking a panic lock comprising two control members, one of which is constantly operable, of the type comprising a reversible electric motor controlling a locking / unlocking element of the other control member of the lock comprising a coupling finger cooperating with a peripheral notch provided on a disc secured to the other control member of a lock to be locked / unlocked, characterized in that than the electric motor carries a crown or a disc integral with the axis of the motor and provided with a plurality of eccentric axial projections, the locking / unlocking element being constituted by the coupling finger pivotally mounted on a plate and by a elastic connecting element integral with said coupling finger at one of its ends and one free end of which is disposed in the path of said axial projections, being able to escape from said projections.
• the elastic connecting element pivots the coupling finger which cooperates with the peripheral notch provided on the disc secured to the axis of the control member of the lock to be locked / unlocked such as, for example , the exterior control handle of a door.
• the coupling finger is pivotally mounted at one of its ends on a projection of the plate, the pivot axis of said coupling finger being parallel to said plate.
• the rotation of the motor in one direction or in the other causes, via the eccentric axial projections, a stress on the connecting element which, in turn, causes the pivoting of the coupling finger around its axis of pivoting on the plate.
• the electrical locking / unlocking control device can be used both with a panic lock, the mechanism of which comprises a single follower, and with a lock comprising a double follower. Depending on the type of lock used, the engagement of the coupling finger in the notch allows the locking or unlocking of said lock.

• the axis of the second control member is not integral with the lock mechanism and the lock is in position lock.
• Controlling the engagement of the coupling finger in the notch by pivoting the coupling finger leads to the securing of the second control member with the lock mechanism, which allows actuation of the lock.
• the lock When the lock is of the type comprising a double follower, it comprises a first constantly operable control member whose axis is integral in rotation with the first follower and a second control member whose axis, having its end integral in rotation with the second follower, comprises a disc provided with a peripheral notch with which the coupling finger cooperates, the plate being fixed on a base and traversed by the axis of said second member.
