Thanks for checking out our switches! This is for a R104 double crossover switch for LEGO trains. It is for use with the Power Functions or other battery operated trains. These are the prototype switches for the Kickstarter coming later this year. There is some assembly required, so please see the provided assembly sheet. Note that this is only for 1/2 of the crossover, a complete assembly will require:
2x R104 Double Crossover Bases
4x Switch Stands
You may need to do a little sanding for everything to fit correctly, this is normal and a function of 3D printing. Also, you will need to source a small rubber band for the point, I've been using the lightweight version of these from Amazon
To attach the cover plate to the bottom, you can use a soldering iron to weld the posts to the cover. Alternatively, you could simply put a bead of glue at each one, and that should hold just as well. Please let us know what you think! We want to get this right!
