Vacuum Bottle Description
Each vacuum bottle (
) consists of two contacts that are enclosed in a
ceramic housing: an upper contact that is mounted to a fixed shaft, and a lower
contact that is mounted to a movable shaft. A stainless steel bellow helps the
vacuum integrity of the bottle, while letting the lower contact move towards
and away from the fixed contact.
