Filed:

Nov 4, 1976

Appl. No.:

5/738763

Inventors:

Terrence P. Goddard - Aptos CA
Samuel D. Webb - Hollister CA

Assignee:

Teledyne McCormick Selph - Hollister CA

International Classification:

F42B 310

US Classification:

102 70R

Abstract:

An ignition device in the form of a linear member which has an internal linear propagation characteristic of a detonation, but a radial heat and gas evolution characteristic of a very fast deflagrating pyrotechnic material not accompanied by a shock or detonation wave. The device uses a central core containing an encapsulated explosive with a surrounding layer, or discrete layers, of a metal-clad pyrotechnic material that is significantly characterized by a class of compounds that are specific simple decahydrodecaborate salts containing the common anion B. sub. 10 H. sub. 10. sup. -2. The outer cladding materials themselves do not functionally ensure a radial deflagration; rather the specific pyrotechnic materials employed ensure a radial deflagration. There are taught specific relationships for components, and a necessary radial compaction.

Abstract:

A dual-in-line switch package having a plurality of momentary contact switching stations and a plurality of indicating lights is disclosed. The switching mechanism of the switches is provided by a close wound coil spring having one end that encloses one contact and another end that is bent by the depression of a pushbutton so that it makes contact with a second contact in order to complete the circuit. The indicating lights may be light-emitting diodes which have lead extensions that are brought out of the package in line with the contacts for the switches. The light-emitting diodes rest on a support guide rail and are held in place in the switch when the cover is snapped on.
