Multi-Output Control

          5 Outputs Triggered by a Single Event

Circuit Diagram-

This circuit is a set of five fets banked together to be triggered by a single input.  The fet circuit is a modified version of the one used in the solid state launch control circuits provided on other pages herein.  There are independent continuity and firing circuits with one common trigger and one common on switch.  each circuit must be independently checked and verified prior to each use to ensure that the fire fet is not shorted.  Common-sense safe practices should always be used.
