Default interesting cutoff switch

found this while looking for work related stuff:
https://www.mpja.com/Battery-Cutoff-...info/34780+SW/
cant say ive ever seen one with a lever. Might make for a hidden rod operated one, easier to kick on off with a foot, might be easier to operate in a push pull fashon for people with arthritis.

$15 and flat rate $6.95 shipping... they sell all sorts of electrical stuff for cheap.

Am I correct in thinking this is probably rated at 100 amps at 24 volts, ...or about 50 amps at 12 volts which is equivalent to about 25 amps on a 6 volt system??

yea im betting thats the continuous rating, not the peak rating and for as little as a starter is used your gonna burn up the starter well before this guy.

thats rated for only 125A continuous but 500 peak.

This is what I am using.. It was given to me by an Auto-electrician friend of mine.. Turn left to isolate battery, turn right to connect.. Very discrete and hidden.

Steve: I used one of those and have a friend who did as well. We both had a real power loss due to the tiny contact area when switch was on. At 6 volts you can't stand much loss. Got worse over time too. Hope yours works for you. Bill

It is bulkier than the usual switch. As far as the capacity, fwiw, it says it is for heavy duty and it only has to cut off the full current once to do its job!

It would be rated 100 amps at up to 24 volts.

Just don't use it in California! As soon as you cross the state line, this device will give you cancer! The official know-it-all State of California says so!!

"Because a reliable electrical system is essential for enjoyment of the car,"


Avoiding burning your car to the ground because of an electrical short qualifies in my book for "essential for enjoyment of the car".



In any case, the cut-off MUST be placed in the GROUND line, and it MUST be placed so that it is easily accessible, not hidden under the floor or inside the hood or some-such.
