Most Jeepers just use switches like these, which work fine—for a while anyway. Trasborg used these in his M-715 for probably the same reason you used them in your Jeep: they were cheap, and they were there at the parts store when you were buying the rest of the parts that day. The problem with them is that they aren’t even a little dust or water resistant. See the crack surrounding the lever? Yeah, that’s a great place for dirt to get into the switch. Over time, dirt and/or water getting in will kill the switch, usually when you need it the most.
