Well they're all very small parts so together they should fit into a tight space 🙂
Maybe just splay the 7805's legs out outside 2 left and inside 1 right, solder the caps across the legs right up close to the regulator and then solder the leads to the power line.
I find that hot glue is an excellent insulator (as long as the components don't get hot), so you could surround the 3 clumped components inside a lump of hot glue to keep it away from other components.
Anything seems possible when you don't know what you're talking about.

@will I have a collection of boxes, I am sure something will be a good fit.

You could probably just solder the blob onto the back of the switch 🙂

@zander, Glad I could help you.. BTW: I've included a ckt schematic for that alternative to a relay to operate an 120 AC load.. The opto-coupler provides isolation between the DC and AC circuits and drives a Diac which controls the the gate on the Triac , (BT136).. Its a basic load control ckt, and the lower part labeled detail, just shows what the circuit in the MOC3021 is doing..
regards,

@inst-tech Cool. Now I know what is inside the SSR i ordered. If I ever need to build a 3rd (2 relays in the package) I can now make it out of it's component pieces.
Some slight differences however. DC power is 12V so I have an LM2596 to drop the DC to 5V for the ESP8266 and the emergency bypass switch.
Thanks for the insight.

No idea what that means.

If you just bent the pins of the 7805 and soldered the caps onto the legs close to the body, you'd have the "blob" I was referring to 🙂
But I think you're better off using the LM2596 you mentioned, as 12V-7V is a pretty steep drop and may generate a lot of heat (depending on the current involved).

@will That's what I figured.
