Universally applicable track magnet for reed contacts in digital or analogue operation. It is simply fastened in the desired position in the sleeper bed with the enclosed fastening screw. Thanks to the screw connection, the track magnet is suitable for various G-gauge track systems and at the same time ensures that the magnet does not pop out of the track. The housing aligns itself horizontally in the track. The functions or sounds assigned to the decoder or sound module are automatically triggered by means of a reed contact built into the locomotive (if available) at the corresponding point (always triggered in the direction of travel with the screw, right). If the screw faces the direction of travel, the left reed contact is released. The new Massoth track magnet is made of weatherproof, UV light-stable plastic.
