An initiator with a housing formed of plastic and a chip assembly for initiating at least one of a combustion event, a deflagration event and a detonation event. The chip assembly includes an electrically-actuated chip and a pair of electric leads that extend through the housing and are configured to couple the electrically-actuated chip to a fireset circuit. The electrically-actuated chip is partially encapsulated in the housing. A method for forming an initiator is also provided.

What is claimed is: 1. An initiator chip assembly comprising: an electrically-actuated chip with a pair of terminals, the chip being adapted to initiate at least one of a combustion event, a deflagration event, and a detonation event in an energetic material that is positioned in intimate contact with the electrically-actuated chip; and a pair of electrical contacts, each of the electrical contacts including a base portion and at least one deflectable spring arm, the spring arm having a first end that is soldered to an associated one of the terminals, the spring arm having a second end that is coupled to the base portion; wherein the spring arms resiliently couple the electrically-actuated chip to the base portions. 2. The initiator chip assembly of claim 1, wherein the spring arms position the electrically-actuated chip above the base portions. 3. The initiator chip assembly of claim 2, wherein the second end of each spring arm is reflexed toward an associated one of the base portions. 4. The initiator chip assembly of claim 1, wherein the contacts are formed of a material conforming to ASTM F15. 5. The initiator chip assembly of claim 4, wherein the material consists essentially of iron, nickel and cobalt. 6. The initiator chip assembly of claim 1, wherein the electrically-activated chip includes a bridge that is adapted to form a portion of an exploding foil initiator. 7. The initiator chip assembly of claim 6, wherein the terminals and the bridge are on a common side of the electrically-actuated chip. 8. The initiator chip assembly of claim 1, further comprising a housing into which the electrically-actuated chip is received. 9. The initiator chip assembly of claim 8, wherein the housing is formed of a plastic material. 10. The initiator chip assembly of claim 9, wherein the plastic material is a thermoplastic. 11. The initiator chip assembly of claim 10, wherein the electrical contacts are partly encapsulated by the housing such that the base portions extend outwardly from the housing. 12. An initiator chip assembly comprising: an electrically-actuated chip having a pair of terminals and an initiating element disposed in a conductive path between the terminals, the initiating element being configured to initiate at least one of a combustion event, a deflagration event and a detonation event in an energetic material proximate the electrically-actuated chip; and a pair of electrical contacts, each of the electrical contacts having a first end, which is soldered to an associated one of the terminals, and a second end opposite the first end, wherein the electrical contacts are configured such that the electrical contacts are deflectable to permit the electrically-actuated chip to be moved relative to the second end of the electrical contacts through a predetermined range. 13. The initiator chip assembly of claim 12, wherein the first ends are disposed in a first plane, wherein the second ends are disposed in a second plane that is parallel to the first plane and wherein the first and second planes are offset from one another. 14. The initiator chip assembly of claim 12, wherein the terminals are disposed on a first side of the electrically-actuated chip and wherein the initiating element is disposed on the first side of the electrically-actuated chip. 15. The initiator chip assembly of claim 14, wherein the electrically-activated chip includes a bridge that is adapted to form a portion of an exploding foil initiator. 16. The initiator chip assembly of claim 12, further comprising a housing into which the electrically-actuated chip is received. 17. The initiator chip assembly of claim 16 wherein the housing is formed of a plastic material. 18. The initiator chip assembly of claim 17 wherein the plastic material is a thermoplastic. 19. The initiator chip assembly of claim 18, wherein the electrical contacts are partly encapsulated by the housing such that the second ends extend outwardly from the housing. 20. An initiator chip assembly comprising: an electrically-actuated chip having a pair of terminals and an initiating element disposed in a conductive path between the terminals, the initiating element being configured to initiate at least one of a combustion event, a deflagration event and a detonation event in an energetic material proximate the electrically-actuated chip; a pair of electrical contacts, each of the electrical contacts having a first end, which is soldered to an associated one of the terminals, and a second end opposite the first end, wherein the electrical contacts are configured such that the electrical contacts are deflectable to permit the electrically-actuated chip to be moved relative to the second end of the electrical contacts through a predetermined range; and a housing into which the electrically-actuated chip is received, the housing being formed of a thermoplastic material; wherein the first ends are disposed in a first plane, wherein the second ends are disposed in a second plane that is parallel to the first plane and wherein the first and second planes are offset from one another; wherein the terminals are disposed on a first side of the electrically-actuated chip and wherein the initiating element is disposed on the first side of the electrically-actuated chip; wherein the electrically-activated chip includes a bridge that is adapted to form a portion of an exploding foil initiator; wherein the electrical contacts are partly encapsulated by the housing such that the second ends extend outwardly from the housing.
