ABSTRACT:
An electrical initiator (10) includes spool halves (12,14) releasably held together by a coiled retaining wire (42). A link wire (42) also holds a spool (46) fixed to spool half (12) against connector body 16 and the other spool half (16). A cavity on the interior of the two spools physically retain a tensilely loaded shaft (18). An electric current passing through the link wire (42) causes it to become brittle and break releasing the spool halves and contained shaft (18).
