do you think these would be safe to use on a car? its mainly for marine applications, but would the bumps, and other vibrations associated with driving loosen the knob controlling power? i'm in the process of designing them, and just thought they might be safe for a double duty. but basically when the green knob is in contact with the base its letting power/ground straight through, but if you crack the knob it kills power/ground. and if you remove the knob it pulls apart for removal of the battery. and sorry for the big pic View attachment 20710 exploded view View attachment 20711 left piece goes on battery terminal, middle piece is plastic to separate flow of current. third piece is the "in" line for power/ground. the knob is only in contact with the first piece (left) when the knob is fully tightened otherwise its separated from the first piece (left) by the plastic insert.
yeah sorry its kinda hard to explain, ill post one up real quick. but basically there is a piece of plastic separating the two pieces of brass, and the only thing controlling the flow of current is the knob itself.
Is this any different than the ones sold specifically for auto use? Example: http://www.griotsgarage.com/product...sic&keyword=battery&sortby=newArrivals&page=1
ha i was looking for another one, my customer gave me one to use to design and i dug around a bit but didn't find something similar so i didn't know if they made them for cars. but i guess that gives me my answer that they will work. edit: and the only difference between the two is the one i have you don't need to modify the current battery terminals as long as they are the post mount or top mount style.
awesome, since before this i have never seen these things, and was kinda pissed that i haven't used them before with all the times i've worked on cars.
These things have been around for years. Most of them have a little bypass wire so that you don't lose your radio station programming and such. http://www.griotsgarage.com/product/car+maintenance/battery+care/quick+disconnect+terminal.do If you're making them from brass, then just throw on a spring washer to prevent the knob from coming loose due to vibration. ~Dan
yeah it has the bypass wire with a fuse for it, just no need for me to design it. i think the only reason i was asked to design this was they are moving production off-shore. but at least now i know these things exist. and thanks for the washer tip.
Good to know those things exist. Disconnecting my boat batteries to charge is a PITA. Error, where in Chaska are you?
i was right of 41 by the cemetery, but i moved back to hutch because being unemployed bills pile up way too fast. and if you need one, i can get them real cheap..
