A disconnect has a housing defining a cavity, a busbar fixed in the housing and extending through the cavity, a piston movable in the cavity past the piston for breaking a piece out of the busbar, and a plurality of metallic filter elements exposed in the cavity below the busbar and electrically connecting with the piece on activation of the disconnect. An igniter displaces the piston in the cavity into engagement with and past the busbar so as to break the piece out of busbar and displace it past the filter elements such that an arc created by breaking out the piece is drawn by the piece away from the busbar and energy of the arc heats and is dissipated in the filter elements.

A pyrotechnic initiator, for example, for inflatable safety air bags of automotive vehicles can include an electrically energizable initiator bridge and a reactive layer on the initiator bridge for liberation of energy upon electrical energization of the bridge. The reactive layer can consist of a combustible metal or a metal capable of liberating energy by alloying with a metal of the bridge.
