Apex button
 

Anyone have any experience with this button sticking? Have it mounted horizontally, with the standard .060 spring, and while sitting in the car practicing it has stuck. Press it a few times and it will come back, then it won't, then partially and stop. Took it apart didn't find anything, one month later same thing happened. Just took it apart didn't find anything, seems to be fine?

I had similar trouble with a Just in Time button which I think is near the same. Changed it out at the track after it messed up. No doubt the lighter spring tensions are the major culprit. I will try a silicone spray lube if there is a next time.
