Yep, it is a dielectric. Just a touch though - not saying spray the thing like you were trying to loosen a bolt. All you need is the lightest coating you can provide. Another trick is when a spray can won't spray anymore, fully discharged, it still has quite a bit of liquid in it. Almost enough to cover the bottom of the can. Pry off the top of the can and you have pourable or brushable wd40. Need a drop or 2? A q-tip or a small brush does wonders.
