When the agent discharge switch is actuated, which component is energized by the electrical circuit?

• A. Squib
• B. Fuse
• C. Relay
• D. Motor

Answer: (A)

When the agent discharge switch is pressed, the electrical power is routed to the initiation device that directly converts electrical energy into a rapid, localized action. That initiator is a squib, a small electrically triggered pyrotechnic device used to ignite a charge that releases or deploys a mechanism. The switch’s job is to energize the squib so the pyrotechnic charge can fire.

The other components aren’t the direct energy recipients in this path: a fuse is a protective element that would blow if the current is excessive, not something that performs the deployment; a relay would be used to switch a different circuit or load, not the immediate discharge action; and a motor is a mechanical actuator that would be used in different systems, not the direct element activated by the agent discharge switch in this context.
