   Cleaning up an old rotary mode switch used for 5v logic levels. It has some   
   kind of grease in it.   
      
      
   …which has always confused me: grease is an insulator (well, the grease in   
   this switch is—just tested and it’s infinite ohms).   
      
   I read that dielectric grease is good to keep contacts sealed against the   
   elements that have high physical pressure (which overcomes any separation   
   provided by the grease) but that signal and other low voltages grease is   
   contra-indicated.   
      
   What say y’all?   
      
   Thanks.
