Push pull pot not working properly

Hi guys, 

Cleaning up this Diablo 2 I just landed and the coil tap switch is a bugger. Was working great with a positive "click", then the nut that holds the pot in place loosened. I gently tightened the nut, adjusted the knob, and now it's on a hair trigger. It pops back to the split coil position if you breathe on it.. Even with the knob off, the switch is popping into the open position now. Grrrrr. I tried adjusting a few times to see if there is a sweet spot, but no dice. I'm thinking I need a new coil tap pot? It just pops back out now instantly. 

If its not a bad switch and I'm just terminally stupid, what am I doing wrong in my adjustment? If I need a new pot/ coil tap what is recommended? 

I find it easier  ajusting two four barrel carburetors on my chevelle then adjusting this effing switch. Lol

Thanks

take some pics of it. If it is pot metalbase (grey) it is a cheap alpha pot, push pull. they do not take much to wreck them. fragile. cheap.

Find yourself a nice brass shaft metal base push push (!) . Push Push are more ready avail now with a higher build quality.

Plus, all you will have to do is tap it to engage or dis engage. Easy Peasy.

Just saw the double post and pics. cheap pot metal alpha pot. find a nice brass shaft push push.
