65 window switch getting very hot??

[coast]

I was reinstalling my driver side window switch on my 65 Riviera when I notices the prongs that plug into the switch plug were very hot. Actually I think that maybe only one as hot, not 100% sure as did not want to test it again to find out. 

 

Does anyone have any experience with this, would it be the plug, the the switch???

 

Is there any place to buy the switch new, I cannot find anything or line?

 

Thanks
