This device comprises two triggers 18, 28 acting on two end portions A, 23 of a floating part 17 which is able to pivot about each of its ends, and driving, via an intermediate portion B, the actuation of a switch 16. Only the combined actuation of the two triggers 18, 28 allows a motor 6 to be put into operation, the release of any one of the two putting the machine in a braking position. <IMAGE>
