I took a drill bit only slightly larger than the screw hole already there and enlarged it somewhat, then used plain old dry wall screws. See pictures. The thing about mounting the throws in such fashion is that about half of them are somewhat removed from the switches themselves, necessitating adding some extension wiring using shrink tubing. Took a while but was worth it!
Thanks for the tip. I didn’t even think about opening the holes. And as you can see in my previous picture, I’m running all the wires from the remote switches to the terminal blocks. Just behind the control panel. I will then run 18-5 thermostat wire from the block to each switch. 3 of the wires are for the switch operation and 2 are for running to my 14v auxiliary power.
Thank you very much for the compliment on my layout. Everything is good so far (knock on wood).
