Baron Throttle Warning Switch
PN: AN3234-2 or
MS25253-2 or NSN: 5930005836646 or
V3-1003
A Baron owner, Jim A., reported finding a
V3-23 switch in his
airplane, it appears to be a 15A version of the
V3-1003. Note
that the JV5 is also listed in the above Baron IPC extract (Item #6) as an
actuator. The JV5 is shown for Code 2 in the IPC and Jim A. reports that he has
a C55 Baron. On early Barons the switch is mounted on the throttle cable in the
center console. On later Barons (like the C55) it is on the throttle body behind
the engine. View the JV-5 Datasheet
