Abstract
A triggering system includes a source lead, a ground lead, primary and secondary actuation circuits, and a serializing switch. Both the primary and second actuation circuits are connected to the source lead and the serializing switch has first and second positions. In a first position, the serializing switch connects the primary and secondary actuation circuit in parallel for actuating primary and secondary cartridge activated devices. In a second position, the serializing switch connects the secondary actuation circuit in series with the primary actuation circuit for verifying that the actuation circuits can reliably actuate both cartridge activated devices.
Claims14
A circuit comprising:
- first and second electrical components;
- and
- a serializing switch with actuate and test switch positions operably arranged between the first electrical component and the second electrical component, wherein the serializing switch connects the first and second electrical components in parallel with one another in the actuate position, wherein the serializing switch connects the first and second electrical components in series with one another in the test position.
A method of testing a circuit, the method comprising:
- connecting first and second electrical components in series using a serializing switch;
- disconnecting the first and second electrical components from one another using the serializing switch;
- and
- re-connecting the first and second electrical components in parallel with one another using the serializing switch.
