Hot button?

[NoobVapure]

So i own a smok telescope. Running a A7 with .6ohms. When I vape, it seems fine sometimes. At other times it doesnt produce as much smoke. instead, alot of the heat goes into the button. I cleaned the connections. but it happens occasionally. My remedy for it is to take it apart and just simply put it back together. then at some point it does it again. May someone know of this problem?
