Bear with me I know nowt about electrickery.
Are the works for the hazard warning in the switch it's self or elsewhere?
I'm wondering if i can just get a switch I like the look of, or do I need matching "Gubbins" from the car?

depends on the switch
Normally you'll need at least a flasher relay.
I can recommend the Haynes Automotive Electrical and Electronic Systems Manual...

im the same chris have no idea but my recent post might help you link

if you have a proper hazard switch then some of the circuit is contained within it. Youll also need a hazard relay.
If you have a Savage switch then the circuit is a little more complicated due to the internals of the switch. Seems there is two or three ways to put
this circuit together, but youll still need a hazard relay!
Would this be in addition to the indicator flasher relay?
I'm looking at the MX5 switch
cheers

I have a flasher relay, hazard relay, Sierra indicator stalk and a Savage hazard switch. Managed to put it all together with no diodes and it all seem so work! Others have Diodes to stop feedback.
