Bursting switch

摘要

An initiator assembly having a base, first and second conductive elements, a first electrically insulating member and an energetic material. The first conductive element, which is configured to receive an electrical input, is coupled to the base and includes a tip. The first electrically insulating member is disposed over the tip. The second conductive element has a bridge that is disposed over the first electrically insulating member. The bridge is configured to vaporize in response to transmission of the electrical input from the tip of the first conductive element to the bridge. The energetic material is disposed over the bridge. Energy produced during vaporization of the bridge is transmitted to the energetic material to initiate at least one of a combustion event, a deflagration event and a detonation event in the energetic material. A method for operating an initiator assembly is also provided.

1. An initiator assembly comprising:
a base; a first contact coupled to the base, the first contact defining a first bridge element; a first electrically insulating member disposed over the first bridge element such that the first bridge element is disposed along an axis between the base and the first electrically insulating member; a second bridge element coupled to the first electrically insulating member such that the first electrically insulating member is disposed along the axis between the first bridge element and the second bridge element; a flyer layer coupled to the second bridge element; a barrel coupled to the base and disposed over the second bridge element and at least a portion of the flyer layer, the barrel being disposed along the axis; and an energetic material disposed along the axis, the energetic material being positioned so as to receive energy from a flyer formed from the flyer layer when the initiator assembly is operated to vaporize the first and second bridge elements via transmission of electrical energy through the first electrically insulating member.
