<p>The invention concerns a device for actuating an electrical or mechanical closure mechanism on a vehicle door and/or shutter, involving the use of a sensor ( 40 ) which responds to nearness or touch. For the device to identify unequivocally whether the sensor control ( 40 ) is actually performed by a human hand or inadvertently by an object, an auxiliary sensor ( 50 ) which, in the form of a detection element has a piezoelectric element ( 51 ), is arranged at the main sensor ( 40 ) contact zone. At least the auxiliary sensor ( 50 ) is covered with a flexible wall ( 28 ) which, upon contact, exerts a pressure on the piezoelectric element ( 51 ) and forms a common actuating location ( 28 ). When said actuating zone is contacted, the main sensor and the auxiliary sensor ( 40, 50 ) emit separate signals which however are evaluated in the same way ( 42 ). When the result of the evaluation is positive, an output signal is emitted, said signal shifting the lock to its locking position. The actuating of the handle ( 20 ) is then ineffective.</p> |
