Title:
ELECTRIC CIRCUIT SWITCHING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/162179
Kind Code:
A1
Abstract:
This electric circuit switching device comprises: a housing; an igniter that emits a combustion gas when activated, a cylindrical space that is formed in the housing; an electroconductive projectile that has a base body which is positioned at a first position in the cylindrical space in an initial state and that is fired in a predetermined firing direction by energy of the combustion gas; and a pair of first conductor pieces that are inserted at a position closer to the firing direction side than the first position in the cylindrical space and that are separated from each other. The projectile further includes a pair of protrusions that protrude from the base body in the firing direction. The pair of protrusions of the projectile which has been fired at the activation of the igniter respectively come into contact with the pair of first conductor pieces, so that a first electrical circuit is switched from an interrupted state to an electrically conductive state.
