No, you shouldn't use a 12V adapter on a switch designed for 9V. It could damage the switch or cause unsafe operation.

I discovered a network switch that functions properly, but I’m having trouble locating the correct 9V adapters. I’ve found options for 12V or 5V, but 5V doesn’t work. Using 12V seems to be the solution. Will it be safe to continue using it in this configuration?
NO FOR GODS SAKE DONT. there's a good chance you're overloading caps, making the SoC's run way too hot, etc... just about any components retailer has a wide range of plug power supplies available at just about every voltage imaginable. it's not worth the 15 bucks to potentially blow up a switch...
It seems the switch displays only 9V, which might mean official details are missing. You’d need to inspect the device and look at its power controller specs, probably requiring some effort. For more flexibility, consider affordable switching power supplies that handle voltages from 5V to 12V—great for various needs. Spending around 15€ on such a solution could be worthwhile.
Despite this, the part could still be rated higher than 9v, yet it would require a heatsink to achieve that, which isn't included since the device is built for 9v. Also, as previously noted, the capacitors are probably rated close to 9v.
