Looking for a SPDT switch

[Townesw]

I am looking for a round rocker switch, SPDT, weatherproof, threaded mount, not lighted, blade terminals. I am not finding anything like this using my usual search methods. 
 

I have removed the shelf from the bathroom vanity and have installed a marine hatch in its place. I now must relocate the pump switch. The factory used what I think is a DPDT panel mount switch and held it in place with a wad of caulk. I want to mount the switch more securely.

I get switches from DigiKey.  Use the more common DPDT like the original one.  Part number CW110-ND.  Haven't seen any with threads and nut, so be carful to drill the hole the correct size.  The problem is that the fiberglass is too thick for the switches to snap in properly.  Therefore some adhesive is needed.   Oh, be carful to keep track that the center wire goes back to center, the other two don't matter.

Good luck!  Geoff

That is why I want to use a threaded body switch. I see that you have run into this problem also. 

I have used panel mounted switches in thick material by finding a hose that the switch will fit tightly into, cutting a short ring out of the hose, and then slipping the ring over the back of the switch to hold it in place, sort of like threading a nut on. 

I have found an adapter to mount a panel mount using a threaded bushing. I had rather use a threaded switch but I may have to use this
