Do i need to fit a dash switch as well as a fluid float switch for sva.

Nope - Fluid float switch tis nuff...

You need to have some means of testing the fluid warning light from the driving seat - most people use the handbrake warning switch connected in parallel.

How do they test float switch for SVA?

He unscrewed the cap on mine and lifted it out then looked at the light, also pressed the domed switch on the fluid cap and pulled the handbrake.

Yup. Unscrewing and pulling out the brake cap is the usual method of SVA testing with the handbrake light as a bulb test function.

This bit with the handbrake confuses me. Can you not have two seperate warning lights, one for the brake fluid and one for the handbrake?
If not, why? Personally, I'd like to know whether I have a leak in the brake circuit, or that I've just left the handbrake on.

If you have two panel lights you will then have to install a separate switch to check the light is working every time you switch the ignition on. It just makes better sense to make the handbrake switch do two jobs. The warning symbol is generally accepted as being the same too.
I find it a nice touch really - ignition on, warning light comes on (so automatic check that light is working) Handbrake off, light goes off.

Playing devil's advocate here, just because the light works doesn't neccessarily mean that your float switch is working so it's best to give it a prod from time to time
