Thread: Idiot proof way to add a kill switch

As the title states does anyone know an idiot proof way for myself to add a kill switch to make my car track legal ?
I know there is something involved with disconnecting the alternator feed but I'm unsure which wire to disconnect.

If you want to do it properly you need to get either a 4 terminal switch with a relay or a 6 terminal switch. The 6 terminal switch has a provision to bleed off the alternator voltage that spikes when you suddenly kill the circuit to the battery and everything else. You can do it with a 4 terminal if you use a relay that substitutes what the 6 terminal relay is designed to do. I am not quite sure how to do it with a 4 terminal, it's just something I've read as an option. Most 6 terminal kill switches are supplied with the appropriate power resistor to bleed the leftover voltage to ground. If you don't do it the 4 with relay or 6 terminal way then you are either shortening the life of your alternator or potentially causing damage to your sensitive electronics. There is also actually another way to use the 4 terminal, but it involves keeping a hot wire to the alternator even when the car is 'dead'.

There are a ton of 1 pole (2 terminal) and 2 pole (4 terminal) switches out there that I don't think are the right switch for most people's applications. I actually have 2 kill switches (one 1 pole and one 2 pole) that I have no use for after realizing that 6 terminal (3 pole) is the way to go.

p.s. most kill switches are mislabled, 4 terminal ones are called 4 pole, 2 terminal ones called 2 pole, 6 terminal ones 6 pole.. this is wrong. Polarity means opposites, meaning there are two sides to a polarity. this is what they mean by pole, so 3 pole = 6 terminal, 2 pole = 4 terminal, 1 pole = 2 terminal

that is the type of switch you are looking, as well as how to wire it
