The Fleischmann 6928 Switch for Double Arm Semaphore Signal is a model railway accessory designed for controlling double arm semaphore signals in model railway layouts.The 6922 is the corresponding switch for uncoupling tracks and the 6925 switch is for controlling 3 way tracks. As a Marklin collector I’m full of admiration for theses Fleischmann switches which are (imo) far superior to anything Marklin made at the time Thiese analogue control switch operates at 15V DC and is made of green plastic, providing a realistic and detailed addition to any railway scene. With its sleek design and reliable operation, this Fleischmann switch is a must-have for collectors and railway enthusiasts looking to enhance their model railway systems.
