Abstract
A vibration adjustable spacer (10) is disclosed. In a preferred implementation spacers 10, 10', 10' are used to damp the vibrational resonance of a number of printed circuit boards (42, 44, 46) in an assembly (40). The spacer (10) has an adjustable snubbing member (30) which extends to abut an essentially stationary surface (7) when the board is accelerated in one direction and a pivotable member (22) operating such that retraction of the snubbing member is impeded when the board is accelerated in the opposite direction.
