The switch limits current flow through itself, and is open to the elements and any corrosion badly effects that type of switch. It may be more trouble to disconnect the battery, but in the end, you save yourself a headache by not using that switch. Mike can use whatever he wants but putting his switch on the ground side will not change much. An inductive amp meter on the battery cable while starting the engine, with and without the switch in place, will show exactly what I'm talking about.
Why that type of cutoff switch is bad is easy to understand when you realize that the motion of electricity is expressed along the outside of a given strand of wire. High current high load applications use many fine strands, and is why a thick welding cable, if cut open, will have very fine strands of wire. With that type of switch, you take a multi-strand high load battery cable and turn it into a single strand wire (the two plates held together in the on position) That creates a choke point.
@MrComaToes You're talking about the "skin effect" and that only applies to high frequencies. At DC it's non-existent and even at the 60Hz mains rates it isn't worth mentioning. A thick welding cable uses many fine strands in order to make a large gauge flexible - nothing else. At DC the only "choke points" are created by smaller gauges, at which some of the energy flowing through the system is turned into heat. Make the gauge small enough and you have a fuse or a fire.
@hoppes9 I'm not an electrical engineer, I'll leave that to the experts. As a practical matter, every connection a wire makes is a potential "choke point". I have had many opportunities to observe the behavior of this exact type of cut-off switch over time. What invariably occurs is the resistance (already higher than a connection straight to the battery) thru the unprotected connection plates, rises to the point it becomes a choke point that can kill batteries starters and alternators.
@hoppes9 Which, is really all I was trying to say in the first place! ...but in any case, it's neither a well made or properly designed cut-off switch.
@MrComaToes Well you know I went to look and there weren't any, then I played it again and there was. I think youtube is just stickin' 'em in there now, here and there and it's hard to know if you're going to get one or not.
@doberfag I try to take them out, but they are putting them in without me knowing now. I'll go see what I can find and dump as many as I can find. Thanks for letting me know

@MrComaToes Right - the "choke point" there is due to corrosion of the open contacts in the switch.
