If the supply-chain fails you and you simply can't find a 10A 1/4" mount toggle, you could use essentially any toggle and pair it with a 10A relay. So each toggle switch would only carry about 0.01 Amps (1000 times less current). You would need a source of 12V DC which could be from a wall-wart you may already have. The relays come in multi-channel (1, 2, 4, 8, etc.) modules and are readily available for $1-2 per channel.
Yes, some extra wiring and such. However, note that the wiring to/from the control panel switches carries only negligible currents so you don't have to run thick "10-Amp wires" to the control panel.
