Re: Toggle Switch
Seems there aren't any toggle switches with a ¾" long bushing. If you're going to thin out the ½" plywood as suggested above, recognize that,
unless you've got a round toggle switch, you'll probably have to take a router to the wood, not just a drill bit. Either that or make a
big hole part way through, and a small hole all the way through. That'll be because of the need to allow the rectangular body of the switch to also go halfway into the wood. And your toggle switch will also have to have its terminals on the back end, not the sides. Even with a round toggle switch, you'll probably have to drill two holes, a larger one part way into the wood for the switch body and a smaller one all the way through for the bushing.<br /><br />Just my 2¢ but maybe you should consider using a push/pull kind of switch since they're made for panel thicknesses up to 5/8 inch, so you'd just have to drill one hole. If push/pull is a viable alternative, go look at the Cole Hersee website, under 'switches':<br /><br />

Maybe that indicates they're suitable for boat use (I have no other basis for saying that)? Good luck.
