Emergency shutoff switch?

piainless has a nice setup I have used on a few rigs https://jet.com/product/detail/1c38a9f19fdd46779317e16d3a1d5b19?jcmp=pla:ggl:vehicles_parts_a1:vehicle_parts_accessories_motor_vehicle_parts_motor_vehicle_power_electrical_systems_a1_other:na:na:na:na:na:2&code=PLA15&k_clickid=8337c259-41bb-40de-86a6-7a11f4248c1b&abkId=403-498026&gclid=CJmVzPWzscoCFdgDgQodtgIC9A
 
On my new build I will be using a tether kill switch that you would typically see on an ATV, this is the one I picked up - http://www.amazon.com/gp/product/B00378K6L0?keywords=Pro%20Armor%20A040021%20Black%20Universal%20Kill%20Switch&qid=1455686419&ref_=sr_1_1&sr=8-1

These are a "Grounding" type switch, when the clip is pulled the switch inside connects to chassis ground. Utilizing a standard relay will allow this type of switch to work in an automotive 12v environment, I have bench tested my setup and it works very well. Mine will be installed so that it will cut power to the entire vehicle by disengaging the continuous duty solenoid that controls all power from the battery. It could also be installed to cut power to the fuel pump and some part of the ignition.

The reason I wanted this type of "kill" switch is the ability to attach the lanyard to either myself or to a stationary point between the driver and passenger seats. Instead of reaching for a button to push I will only need to "sweep" my arm across the lanyard which will give a much larger target to hit in a panic.

I also intend on installing an oil pressure switch (the style that would turn on an "idiot" light) that will also act as a kill switch if I ever lose oil pressure, ie. rollover or mechanical failure.

you got a link to the continuous duty solenoid you will be using? Safe to run the winch through?

The one I have been using for 3 years is a 100 amp from a CaseIH tractor. I have the oem unit (pn:107655C1) this is an aftermarket replacement http://www.nationwidepartswarehouse.com/product-p/1700-0208.htm

There are other models that were used on various automotive applications that are 50-75 amp rated.

My winch doesn't run through mine since it draws well over 100 amps at its rated max. The winch has enough solenoids that can cause problems, didnt see a need to add another. LoL

Quite a few options here http://www.amazon.com/gp/aw/s/ref=is_s?rh=i%3Aaps&k=continuous+duty+solenoid+12v

You could probably get by with a 200 amp rated model if you really wanted to incorporate the winch.

My personal choice would be a battery disconnect to kill power to a winch. Most can easily handle the power draw from a winch since they utilize a mechanical connection.

The CD solenoid is great as a safety option since it allows you to kill power to all fans, pumps, and ignition with a single switch.
