It allows trains to trigger events as they pass specific points on the layout. You can connect it to signals, station lighting, level crossings, or sound modules.\u003c\/p\u003e\n\u003cp\u003eMany hobbyists use reed switches to build realistic operating sessions. For example, a passing freight train can automatically activate a yard signal or switch platform lights without manual input.\u003c\/p\u003e\n\u003cp\u003eThis adds operational realism and reduces the need for constant controller use.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHow to use it\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eInstall the reed switch under or between HO track sections. Position a small magnet under a locomotive or wagon to activate it.\u003c\/p\u003e\n\u003cp\u003eConnect the switch to your chosen accessory circuit such as LEDs, relays, or a DCC accessory decoder.\u003c\/p\u003e\n\u003cp\u003eTest placement before final fixing to ensure reliable activation. Basic soldering tools and wiring may be required depending on your layout setup.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis is an electronic model railway accessory. It requires basic wiring and is not a toy.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Marklin","offers":[{"title":"Default Title","offer_id":46683861778588,"sku":"MK7555","price":27.99,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0585\/9095\/3628\/files\/MK7555.jpg?v=1776702105","url":"https:\/\/www.hobbyco.com.au\/products\/ho-reed-switch","provider":"Hobbyco","version":"1.0","type":"link"}
