You can lubricate any ABS parts with clear silicone (not silicon) grease that is commonly available in electronic stores and it wont have any effect on the plastic parts, like a mineral lubricant, and will have no effect on electrical contacts other than preventing corrosion.
Mine is Dow Corning MS4 (now DC4) silicone compound.
Only a small amount is required, so it lasts forever.
Highly recommended for all such jobs.
