1. Arrangement for actuating an electrical or electromechanical closing device (10) on a door (12) and/or a hatch of a vehicle, with a handle (20), which is used to open and/or to close a lock (30) provided on the door (12) and/or hatch, with at least two sensors, which, upon approach or contact, transmit separate signals, the signals nevertheless being evaluated (42) jointly, with the result that the lock (30) is switched between an unlocked position and a locked position, where, in the unlocked position, the actuation of the handle (20) is functionally effective for the lock (30) but is not functionally effective in the locked position, wherein a capacitive main sensor (40) and an auxiliary sensor (50) equipped with a piezoelectric element (51) are arranged one on top of the other at a common actuating point;

  • in that the common actuating point consists of an elastically resilient wall (28), which, when contacted, exerts pressure on the piezoelectric element (51); and

    in that a successful evaluation (43) of the signals coming from the main and auxiliary sensors (40, 50) switches the clock (30) to its locking position.
