Wiring Diagram for two tone Snailshell horns

I have a pair of 'snailshell' horns. They are 12v and seem to draw quite a bit of current. I would like to wire them to give the 'Dee Dah'sound. I am hoping to wire them as stand alone with their own battery and use some sort of centre off two way sprung switch.
All of the diagrams I find show relays but none seem to show a diagram that gives seperate horn activations. Do I presume the relays are because of the current drawn? Does anyone have a diagram and even better, know what relays / switches I will need?

If you have space for a chunky switch (momentary SPDT) on the dashboard then connect the negatives of both horns to the battery negative. Take the positive of the battery through a 10A fuse and to the centre of the switch. Each side of the switch goes to the positive of each horn.
If you are using a miniature switch that are normally used on handsets then you will need two relays. Circuit is similar to above but with either side of the switch feeding each relay coil.
(10A fuse should be enough but if it blows uprate it to 15 or 20A)
