Seeburg M100A plate switches

Can anyone tell me if the frame of the plate switches are supposed to be flat or are they slightly curved back?

I had 2 bad plate switches with the copper part that holds the plunger broken off. I got an old unit from Bill up in NAPA, CA and that unit had 6 of 10 plate switches with the frame broken away. The copper with nothing backing it up at the top.

If the plate switch backs are supposed to be flat then I am going to solder the ends where they are riveted. I think the rivets are too low in the original design and they are bending and breaking at that point.

See photos.

Thanks, James

Hi Ron, I have just enough with the used block I purchased from Bill up in NAPA. Although of the 10 plates I only got 4 that are any good. If you have some NOS ones around, can you look and tell me if the backs are flat or angled away from the brass contacts?

Thanks, James
