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 and positioned at a predetermined first position in the tubular space in an initial state; a piston fixed to the projectile and disposed in the tubular space interposedly between the igniter and the projectile, 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 projected integrally with the piston upon actuation of the igniter comes into contact with each of the pair of first conductor pieces, switching the first electric circuit from an interrupted state to a conductive state.
