Cramolin R100L Replacement - Electrical Switch Contacts

I am in need of a lubricant for electrical switch contacts. These switches are part of a high accuracy decade resistor, with tolerances in the parts per million (ppm).

I have used Cramolin in the past with good results, but my maintenance book (written in 1970) calls for "a low-conductivity oil (Viscosity Oil Co., No.7069, available from ESI as Part No. 13500)." The company is no longer in business.

Can you give me some info on products you sell that would be a good substitute for my needs? Any info would be appreciated.
