Abstract
Between a rocking lever controlled by a striking pin of a cartridge and a resiliently loaded actuation knob of an alarm micro-switch, there is interposed an arm mounted on a pivot which pivot is spaced from the movement axis of the knob with result that the knob is engaged by the arm virtually without any mutual lateral sliding therebetween.
