This coupler is for a close-coupled connection between cars with single-conductor current transmission. It can be used in the close coupler pocket for all modern 26.4 cm / 10-3/8" and 27 cm / 10-5/8" long Märklin H0 cars with a guide mechanism. This means that a single pickup shoe will be enough for a consist of lighted cars. In addition to two current-conducting close couplers, each set also has the hardware for current transmission through the guide mechanism as well as the terminal clips for the interior lighting wire for one car. Coupling and uncoupling of the car with these couplers can be done on a layout manually.
Each package has 2 current-conducting close couplers and the hardware for the current transmission to convert a car. Installation instructions are included.
The 72020 current-conducting coupler, which can be uncoupled, is an alternative or conversion option for the current-conducting rigid coupler drawbars in the 7319 conversion set.
