Air Horn Yankee Horn 12V/24V compatible Magnet switch, general purpose! Usable for a wide range of air horns and Yankee horns! Operated directly from the battery! Operation confirmed! It was dull, so I lightly polished it! Since it is an old item, please purchase only if you understand. Therefore, it is a junk item! Separately from this product, a magnet switch made by Kitahara HKT Kitahara Seisakusho is also sold. Bulk sales are also possible! If you wish to purchase in bulk, please comment before purchasing.
