Fitting air horns to 02 defender

Surely you only need an on/on switch if you want to install the air horns as well as continuing to have the option of using the original horn. If the OP just wants replace the original horn with the air horns (providing they are the road legal version) then he can continue to use the original horn switch into a relay?

I'm not an auto electrician, but shouldn't the on/on switch be first in the circuit, diverting the batt from the horn button on steering wheel to either the existing horn or the relay for the new one?
