usb / 3.5mm module size
 

Can anyone advise what correct size switches would fit where the standard USB / 3.5mm jack module is in the front pocket?

I want to put a on/off/on 3 way rocker in there to toggle camera feeds, but want the switch to look as OEM as possible.

Mcmaster has drawings of all of their switches which you can then measure the opening you want it to fit.

after a bit more research I'm 99.9999% sure these are standard current toyota switch size of 32.5mm x 22mm
