Title:
ELECTRIC CIRCUIT SWITCHING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/162176
Kind Code:
A1
Abstract:
This electric circuit switching device comprises: a housing; an igniter for releasing a combustion gas upon activation; a cylindrical space formed in the housing; an electrically conductive projectile that is positioned at a predetermined first position in the cylindrical space in an initial state; a piston fixed to the projectile and located in the cylindrical space so as to be interposed between the igniter and the projectile, said piston configured to be launched in a predetermined launching direction by the energy from the combustion gas; and a pair of first conducting strips provided in an inserted condition spaced apart from each other at a position in the cylindrical space farther in the launching direction than the first position. The projectile is launched together with the piston at the time of activation of the igniter and makes contact with each of the pair of first conducting strips, whereby a first electric circuit is switched from a cutoff state to a conducting state.
