Abstract
A shock absorbing mechanism for protecting a fragile quartz crystal includes a Teflon coating on the internal surface of the crystal enclosure. The enclosure is provided with a plurality of detents arranged so that when the crystal is shocked in its most fragile plane a plurality of these Teflon coated detents are struck simultaneously to distribute the shock across the surface of the crystal.
