What is this switch for

[72 BLUE 400]

69 superbee has a am/ fm radio and the switch that looks factory any body know what it’s for

WAG, add on electric fuel pump? Certainly not OEM.

Power antenna ?

 

[Dave6T4]

My guess would be add-on power antenna, with switch's proximity to radio.

Did you trace the wires to see where they go?

For example:
Auxiliary lights
Siren
Alternating headlight flashers
Rear window defroster
Trunk decklid release
Stereo amplifier
Dome light shutoff for when doors are open
Taillight and brakelight shutoff

Switch is not centered. Looks like it was owner added.
