Rocket Firing Distribution Controller Mk 3, US, Navy F4U, TBM
Here is a Rocket Station Distribution Box which appeared in WW2-era F4U Corsairs and TBM Avengers of the US Navy, and possibly others. It is labeled for the US Navy.
Once switched On, the controller dictates how the rockets are fired when the pilot depresses the rocket firing switch located on an adjacent panel. So, when the firing switch is depressed, either:
a) no response (if the Safety Plug has not been inserted)
b) firing of the selected rocket pair (i.e., "Station") per that indicated in the Next Station window, or
c) if Single is selected, manually firing rocket pairs upon depressing the firing switch each time, or
d) if Auto is selected, automatically firing all rocket pairs in 10 second intervals,
e) if the Safe switch is selected, rocket detonation will be delayed after impact; if Arm is selected, detonation occurs upon impact.
