A method, system, and apparatus for restraining a firing pin using a bushing for use in a downhole switch that is armed using the explosive energy of a previously detonated shaped charge.

Methods to trigger the Hybrid primer cartridge in electro-mechanical and full electric mode using modified locking chamber with electric power contacts that can supply the modified bolt with very high-voltage electric power supply where the contacts are sufficiently insulated to avoid any leakage. Modified bolt with power contacts on the locking lugs such that when in locked position it can receive power from the chamber's power supply contacts and apply the electric power to the electrode pins of the hybrid primer through the contacts on the face of the bolt. An electric switch that is controlled by the movement of the hammer or striker converting the mechanical movement to simultaneously control the electrical triggering of the primer thereby eliminating need for microprocessor or microcontroller units. A hybrid hammer device which has high-voltage power pulse supply and return contact points surrounded with adequate electrical insulation wherein one of the contacts may be such that it acts like an electrical switch which will be closed when the hammer strikes the hybrid firearm firing pin and bolt. A bolt which can receive the power from the hybrid hammer through the contacts in the aft or through the insulated firing pin contacts.

A smart store communication interface (SSCI) squib of a countermeasure expendable. SSCI squib also includes a first electrical network. SSCI squib also includes a second electrical network that is isolated from the first electrical network. SSCI squib includes a fire pin contact that operably engages with the first electrical network and the second electrical network. The SSCI squib is configured to one of ignite a propellant loaded inside of a housing of the SSCI squib and communicate with a processor of the countermeasure expendable in response to receiving at least one electrical signal at the fire pin contact.

Various systems and methods for leveraging legacy countermeasure dispensing systems (CMDSs). The legacy CMDSs are leveraged through the expansion of breechplates and magazines in a CMDS by expanding the amount of expendables carried by a CMDS while still maintaining the legacy sequencer and dispenser in a legacy military platform, such as an aircraft. In addition, various circuitry systems are included in a circuit card of the breechplate for duplicating and/or expanding the firing lines provided in a legacy CMDS.
