Replacing Stock Ignition Switch

Hi all, sorry in advance for the long post, hopefully my description of what I am trying to do will be as clear as mud at the end of reading this!

I am currently in the process of re-wiring my 1969 VW beetle and want to replace the stock ignition switch with a combination of toggle switches and relays and was wondering if my theory here is sound...The original switch is getting a little tired and rather than replace it, I wanted to do something a little different!

I want to use 2 toggle switches (1 for the Accessory position and 1 for the Ignition circuit) and a momentary push button switch for the start circuit to mimic the ignition siwtch. All 12v battery feeds will be be run through a seperate kill switch to isolate the toggle switch feeds and 12v battery common relay inputs...(effectively like using a key for the ignition switch).
All switches are from ignited performanc(www.ignitedperformance.com).
The kill switch is rated at 500amps, toggle switches are rated at 10amps and the push button starter switch is rated at 10amps. All relays are SPDT, 12VDC 30amps from local auto parts store. The rest of the car has been re-wired with a American Autowire kit from Watsons Streetworks.

So for the accessory circuit, my wiring would be like this.... 12v low current feed switched through toggle switch to relay coil term 85 to energize the relay coil. Relay term 86 to ground. 12v High current fused battery feed to relay common term 30. N/O relay term 87 to accesory wire, (accesory circuit of watsons kit)

For the ignition circuit, the wiring would be like this......12v low current feed switched though toggle switch to relay coil term 85 to energize relay coil. Relay term 86 to ground. 12v high current fused battery feed to relay common term 30. N/O relay term 87 to ignition wire (ignition circuit of watsons kit).

For the start circuit, I only want the push button starter switch to be able to engage if the ignition toggle is in the "on" position....so wiring would be like this.... 12v low current feed from output of ignition toggle switch, through the momentary push button switch to relay term 85 to energize relay coil. Relay term 86 to ground. 12v high current fused battery feed to relay common term 30. N/O relay term 87 to starter wire (starter solenoid)

Does all this sound OK and would it work? How safe would this be...ie: how reliable are relays in this type of situation? Can I daisy chain all my common battery feeds to each relay (term 30) back to one fused point for ease of wiring, or should I run seperate fused feeds to each realy? Can all my relay coil grounds (term 86) be grounded back to one point also?

Thanks in advance for reading my post, and any advice/suggestions offered.

Thanks Hymer.....I've actually converted over to an internally regulated alternator so should be fine in that respect.... :)

As for the relay, I thought as you did originally that the push button starter would be OK (rated at 10amps and all), but the instructions that came with it recommended a relay so I thought it is cheap and easy to install so why not.....

lol, your car is going to be like starting up an airplane. sounds fun.
