A package comes with 10 pieces. These sockets can be used with the standard plugs and sockets from the 71400 assortment.
These plugs and sockets cannot be used with the earlier versions (package, item no. 7130). The sockets will fit as plugs with some limitations into the sockets on the older versions of control boxes. The control components and decoders in the current Märklin program have been changed to the new standard for plugs and sockets.
