Projects Column drop/lock/ign.question

I completely went through my column drop/lock/ign. assembly. Before I put it together I am assuming that the mover parts like the column lock sider, and switch it's self as well as the end of the key need to be lubed?
Should these parts be approached as a lock? Where you use only graphite powder as a lube? Or should some of these parts need some lithium type grease?

 

Slider grease, Switch shouldn't need any, it is a Little electric light switch.

 

I used dielectric grease in the switch, lithium in everything else except the lock cylinder.
