Mounting toggle switches in 9mm plywood

switchmounting

The problem: Fitting a toggle switch in a 9mm plywood baseboard. You can't just drill a hole as the threaded area on the switch is also 9mm tall so the retaining nut won't grip.

Solution: Drill half way through the wood with a 12mm spade bit. The go all the way through with a 6.5mm normal bit - the spade will leave a guide hole in the centre.

Clean up with sandpaper, knife and the spade bit twiddled in the fingers.

Result: Nicely recessed toggle switch held in place perfectly.

Sounds simple but thinking this up took me a couple of days!

I hope that's not the working side!

When I do that, I use a 3/4" spade on the REAR of the wood, so the body of the switch can sit inside that depression . Then the top of the switch comes through the wood as if the wood were exactly the right width...

Sadly there's only 7cm under the surface so no space for a drill. Otherwise I'd have done it your way!

Planning is a wonderful thing. I must try it one day..
