yes throw bar....the ones that work correctly don't have the plastic throw bar it has metal piece between rails where the other has the plastic.

no not frog....I tried to post a pic of the 2 but it wouldn't let me........one is solid metal between switching rails(end of rails that move in the switch also it lays on top of the ties) the other that doesnt work properly has a plastic piece that slides the rails between the ties.

plastic spacer between the switch rails not at rail connection point

All grey road bed and I use DC, no reversing loops and one does have a platic spacer at the end of switch rails

I have two different types of EZ Track switches 1) It is solid metal at the end of the switch rails......2) It has a plastic spacer at the end of the switch rails. I m having problems of continuous power to spurs and yards and also no power to these with the second switches 2). any suggestions to what is going on... first switch 1) cuts power and powers like it is supposed to.
