Abstract
Some embodiments pertain to an initiator support assembly that includes a casing and one or more initiator leads extending from the casing. The transmission of current through the initiator leads detonates an explosive charge within the casing. The casing includes a flange and a dampening member attached to the flange. The dampening member is between the flange and a structure where the initiator support assembly is mounted. The dampening member dampens shock that would otherwise be transferred from the structure to the initiator support assembly. In another example embodiment, at least a portion of the casing is formed of an interior wall, a dampening layer covering at least a portion of the interior wall and an exterior wall. The dampening layer dampens shock to the initiator support assembly that would otherwise be transferred from a structure to the initiator support assembly when the exterior wall is mounted to the structure.
