The wipers on these rest in the flange way and get bent up on switches. I've straightened them 3 times now, the last working for 45 seconds before again shorting out on every switch. This appears to be a flawed design. Has Bachmann issued an upgraded part for this, or does anyone have a suggestion as to how to remedy this? I looked at possibly flipping them over by switching sides, but they are notched for the gear, so that is not an option.

Any he!p would be appreciated
