Abstract: A switch, particularly an apparatus switch having at least one movable contact element is described. The switch can be moved by an activating member from a shut-off position into an operational position, and includes a housing that has at least one receptacle for an opposing contact element that can be contacted by the movable contact element in its operational position. The receptacle is initially unequipped with a contact but is formed to subsequently receive a contact from the outside.

Abstract: A unit plug which is combined with a voltage selector and a fuse supporting device to form one component is disclosed which has, as a voltage selector, a roller-like pressure hull adjustable in different angular positions and contact pieces movable against the force of springs which, depending upon the angular position of the pressure hull, are held in different combinations by the pressure hull resting against counter-contact pieces assigned to them. The fuse supporting device is provided with at least one exchangeable fuse holder for a fine-wire fuse as well as with contact pieces which rest against the contact caps of the fine-wire fuse when the fuse holder is inserted.
