Hello there, first time owner, new to the board, ect. My boss recently won the pink panther machine (I'm assuming it's a pachislo machine, I've never heard of them, but my google searches lead me here) in question and we basically have bad contacts on the stop reel buttons and they are not working 100% of the time (mostly 1% of the time on one of them). I was wondering if there is a way to clean the buttons to get a better contact on them, or if there was a good resource for getting replacement buttons? Thanks in advance.

I've attached a picture of it as a reference if that helps.
