ABSTRACT:
Maintained contact push-button, particularly an emergency stop button, provided with a padlocking accessory.The button has a barrel and a movable head. The accessory has a sleeve fixed with respect to the barrel and having an inner shape matching the upper part of the barrel, and a movable ring. The ring has at least one aperture for the passage of padlocks on its upper edge, and is mounted on the outside of the sleeve so that it can move between a lower inactive position and an upper active position, by a movement which is limited by means of stop elements, in such a way that the head is left free in the lower position and the upper edge of the ring rises above the head in the upper position.
