The invention relates to a suspended control device (20) which is suspended by means of a control line (1, 24) connected to a unit to be controlled (21). Said suspended control device is especially a control switch or a suspended push-button switch for controlling hoisting equipment, the control line (1, 24) comprising electrical lines (2) for transmitting control signals, and a traction relief element (22) which is supported at the top, on the unit (21), and used to absorb weight and tractive forces. The aim of the invention is to provide a suspended control device (20) whereby the length of the control line (1, 24) can be easily changed. To this end, a storage element for receiving and releasing a defined length of the electrical lines (2) is provided behind the region wherein the traction relief element (22) is supported, seen in the direction of the unit (21) from the suspended control device (20).

L'invention concerne un dispositif de commande suspendu (20), qui est suspendu à une unité à commander (21) par l'intermédiaire d'une ligne de commande (1, 24), notamment un commutateur de commande ou un palpeur suspendu servant à commander un engin de levage. La ligne de commande (1, 24) comprend des lignes électriques (2) servant à transmettre des signaux, ainsi qu'un dispositif de décharge de traction (22) qui prend appui dans la partie supérieure, au niveau de l'unité (21), pour absorber des forces exercées par des poids et des forces de traction. L'objectif de l'invention de créer un dispositif de commande suspendu (20), dans lequel la longueur de la ligne de commande (1, 24) puisse être facilement modifiée. A cet effet, un élément de stockage pour les lignes électriques, servant à recevoir et à distribuer une longueur de ligne donnée, est placé, vu à partir du dispositif de commande suspendu (20) en direction de l'unité (21), derrière le point d'appui du dispositif de décharge de traction (22).
