Abstract
Methods of controlling fluid flow (e.g., flow of liquids, water vapor and gases) through switch members, e.g., switch buttons, which are used to seal an interior cavity of a surgical handpiece are provided. The switch members provide improved sealing properties which prevent gas and water vapor transmission across the switch member and into and out of the sealed internal switch chamber. The switch members are also resistant to puncture due to striking by tools or cleaning instruments, or the like.
