The only thing that comes to mind is that Vaseline is petroleum based and should not be used on or in close enough proximity to get onto anything rubber, as eventually it will degrade rubber. A potential example would be the self canceling turn signal system that partially relies on a rubber pellet inserted into the switch. Silicone lube on the other hand has no detrimental effect on rubber. I still have and use a small tube of Harley Davidson Electrical Contact Lubricant left over from when I had a Harley. It is clear, and about the consistency of Vaseline. Although ingredients are not listed on the tube, I imagine it is probably silicone based.
