Abstract A match type electrical initiator which has a 1 watt/1 amp nofire characteristic utilizes an insulated dual conductor flat cable, such as polystrip cable, as an integral part. The initiator has a head portion and a body portion, the body portion being the insulated dual conductor cable whose conductors terminate in the head portion. The head portion is comprised of the conductors which have been bared of insulation, fitted with a bridgewire fastened therebetween, covered with an ignition material with about 90% by weight of the material being comprised of a stoichiometric mixture of lead thiocyanate, potassium chlorate, and charcoal and with about 10% by weight of the material being a binder, and covered with an external epoxy adhesive coating which serves to seal the head portion thereby obviating the requirement of an initiator case. The initiator can be manufactured in mass production to a thinness of about 0.070 inch which makes it ideally suited for initiating action of a destruct unit for rocket motor cases for weather rockets. The small initiator can be easily fitted into the approximate 0.100 inch space envelope of the honeycomb of a rocket motor case.
A MATCH TYPE ELECTRICAL INITIATOR COMPRISING: I. AN INSULATED DUAL CONDUCTOR FLAT CABLE HAVING A HEAD PORTION AND A BODY PORTION, SAID CONDUCTORS EXTENDING THROUGH SAID BODY PORTION AND HAVING FIRST ENDS TERMINATING IN SAID HEAD PORTION, II. INSULATING MEANS COVERING SAID BODY PORTION, III. A BREDGEWIRE FASTENED BETWEEN SAID CONDUCTORS IN SAID HEAD PORTION, IV. AN IGNITION MATERIAL COVERING SAID HEAD PORTION, AND IGNITION MATERIAL BEING COMPRISED OF ABOUT 90% BY WEIGHT OF A STOICHIOMETRIC MIXTURE OF LEAD THIOCYANATE ABOUT 35.6 PARTS, POTASSIUM CHLORATE ABOUT 44.4 PARTS, AND CHARCOAL ABOUT 20.0 PARTS, AND OF ABOUT 10% BY WEIGHT OF A BINDER MATERIAL COAPRISED OF LEAD STYPHANATE IN RATIO OF
