yeah i know the theory, i was just hoping someone might make a sealed switch, (no terminals to solder, or casing to worry about) that i could splice inline on a 12v low current circuit, just like you can splice in the inline fuses. With all the switches i've found so far (like the marine switches you linked to), i'd still be left with exposed terminals on the back which i would need to cover in heat-shrink, or mount the switch in a container of some sort making it bulky. Also, they are not really "in-Line" so would not hide away as well. Basically, i have an alarm on my bike with a hidden switch that lets me cut the power to prevent battery drain. the switch i have at the moment is not great, so i was looking to replace it, and didn't want anything too large. Ideally something like an inline fuse holder, but a switch would be great.. I guess i could just use a fuse holder and pull the fuse, but thats not ideal as i could easily lose the fuse
