ELECTRIC CIRCUIT SWITCHING DEVICE

Abstract: an electric circuit switching device includes a housing; an igniter configured to release a combustion gas upon actuation; a tubular space formed in the housing; a projectile having conductivity, including a base body positioned at a first position in the tubular space in an initial state, and configured to be projected in a predetermined projecting direction by energy of the combustion gas; and a pair of first conductor pieces provided inserted, in a spaced apart state, into the tubular space at a position closer to the projecting direction side than the first position. the projectile further includes a pair of protrusions protruding from the base body in the projecting direction. the pair of protrusions of the projectile projected upon actuation of the igniter respectively come into contact with the pair of first conductor pieces, switching the first electric circuit from an interrupted state to a conductive state.
