I am replacing the 12v incandescent wing recognition lights (2) and nose landing light with a Flyleds array in the nose rated at 10 amps and the two wing lights at 2 amps. I would like to maintain the two panel mounted SPST switches from the previous installation but to operate the wigwag circuit and switch all three to constant "on", one of the switches has to be a DPDT. Theoretically, I could power a DPDT relay from the SPST switch but searching Mouser and Digikey I am finding a dearth of possible candidates. Another option would be to use two SPST relays of which there are plenty and operate them both simultaneously via the panel switch. I would appreciate advice on the variables for the contact materials, coil resistance, etc. for this application.

If two SPST relays will work, then why not one DPST relay?
Mouser #:769-ACTL3CR3V
Silver Alloy contacts are good for power applications.
Gold contacts are for small signals, not power.
Coil resistance should be greater than 100 ohms. Otherwise the relay will get too hot.
Here is a DPDT from Digikey. Part number: A102CS12VDC
Looks like both relays above have pins that require soldering.

It would be helpful if you could post a schematic
of your proposed wiring. Verbal descriptions of
schematics are often mis-interpreted leading
to the wrong advice.

Un impeachable logic: George Carlin asked, "If black boxes
survive crashes, why don't they make the whole airplane
out of that stuff?"
