I'd suggest Deoxit istead of WD-40; it's purpose made and does what it promises.

  Yes, Deoxit can often be considered technician-in-a-can. Many electronic repairs need nothing more. Most switches do need to be exercised for them to continue to go on & off as designed, and have a service rating for the minimum number of cycles, usually thousands. When you don't even switch once a decade you're not wearing it out, you're actually not even breaking it in. Even though DIPs and other set-and-forget switches are easily forgotten, this is good to remember. When accessing DIPs take the opportunity to spray contact cleaner and excersice them all a number of times before returning them to the desired settings. Without Deoxit I prefer pure isopropyl alcohol and almost never WD-40 which is formulated for water displacement and light but cutting lubrication instead of contact conditioning.
