Cruise servo

Hi guys ... just trouble shooting my '79 460 cruise prob ... should the servo hold a vacuum if you push in the plunger and hold your hand over the vacuum port?
Can the on - off switch on the steering wheel be bench tested? I guess the harness behind the drivers a/c vent can be light tested with the on - off switch , right?

Thanks

The servo requires constant vacuum to operate. I don't know anyone who can bench check the switches. I've never had any of my switches fail.
