Do winches need an isolator switch?

I have seen on a lot of places on the internet that it is recommended winches are mounted with an isolator. Can anyone explain why this is needed as am a complete immature when it come to electronics?
 
Yes they do. The reason they need one is because the have no relays; therefore if there I a short circuit somewhere the thing will burst into flames.
 
It's not that they need it to work. They will work without one. However, it is good to have it on there as it can save you from a fire. If you need the winch asap I would mount it on there and leave the positive wire disconnected and connect it only when I need the winch
