I wish I had known this before I spent 40.00 on silver conduction greast that Super T recommended. This is just for the where the switch connects and the body that is passes through. Are you saying I don't have to use this.
Sounds like you got the correct stuff. I don't know about these other cheaper brands. Grainger has great prices, so when i see other brands going for far less, i question whether they are truly the same. Some of them say they are not electrically conductive, but here is a copy and paste from the one i recommend:
" Silver Conductive Grease, Syringe Dispensing, Size 6.5 g, Size/Net Weight 6.5 g, Color Silver, Temp Range -70 to 485 F, Silicone Base, Electrically and Thermally Conductive Grease, For Maximizing Electrical Conductivity In Electrical Circuits, Protecting Connections and Maximizing Thermal Conductivity In Heat Sink Applications"
Heres the link:
