I read the recent thread about switches but didn't see reference to one with a fuse as in the picture below. What does the fuse connect to and what is it supposed to protect?

Re: Battery switch
If i'm not mistaken, you connect that wire to the other side of the battery clamp so it provides power to keep your clock working and radio presets.Turning the green knob disconnects the battery from starting engine.

Re: Battery switch
That device is for computer controlled cars. The small fused lead keeps the computer and radio pre-sets electrically energized so they don't lose their memory through a lack of power. The fuse protects the vehicle electrical system and will blow if one forgets and tries to start the car with the main switch disconnected.TerryComment

I would need a large box of fuses. I wish I had a dollar for every time I forgot the battery switch.

Fuses are cheaper by the box *NM*

Re: Battery switch
Doesn't this defeat some of the purpose? The battery switch is obviously not a theft prevention item as the thief can easily turn it on. The use is to disconnect the battery to prevent the battery draining and/or a fire from a short. The fuse should blow if there is a short to prevent a fire, but it will still let the battery drain until it is dead.
If it is a fire you dread, then I suggest you do a thorough inspection of the wiring. Most car fires I have seen were when the owner was driving them, so the disconnect wouldn't do much. And even being with them, most drivers were incapable of stopping the fire. And those that did get stopped had about 10 or 20 lbs of dry chemical all over the car.Comment
