Hire an electrician

Elon Musk plays a huge role in advancing Elon Musk's image and popularity.

He's the CEO of what, six companies now? It must be an incredibly ceremonial position, especially since he has all this time to interact with sycophants.

That's great!

It might help you to not think of switches as a device that uses power. The old-style switches (single-pole, 3-way, 4-way) are really points in the circuit that use no power and break the connection. Functionally they are like circuit breakers.

They don't use a neutral because power is only passing through the switch, not being used by it. Electronic switches are different and yes, they use power and a neutral. Neutrals are your return path to the breaker box.

Making a splice for all your neutrals together is common. You'll also see it happen at a switch where your hot wire forks to feed both a switch and then leaves the box to feed a plug with constant hot. Keep in mind that electricity doesn't care what color the wire is and sometimes the original electrician doesn't care either.

If you really want to know more, study parallel circuits and series-parallel circuits. This is the science behind electrical work. The pigtails coming off a spliced connection is an example of power feeding along "parallel lines."

The switch being "in front" of the lights in a similar circuit is an example of a series-parallel circuit if I recall correctly.

I also recommend you study the difference between single pole switches, 3-way switches, and electronic switches if you can afford the 20 minutes.

OK, do you know what a pigtail is? Make a couple pigtails off the couple white wires that are nutted in the back and take each pigtail to one device. Use at minimum 14 AWG wire, or 12AWG. But take note. That 3-way on the right is using a white wire to carry current, probably as a runner or traveler. Check the other 3-way switch in the room and you'll see it there, too.

This should show you that a white wire is not always a neutral, ESPECIALLY in homes. Ok?

Also, if your smart switch is a dimmer, you ought to turn the circuit off, just in case you haven't done that. Hooking an electronic dimmer up "hot" will kill it with inrush current.

The white wire that's wirenutted and stuffed in the box, is could be your neutral for a switch on the left. Trace that wire to other boxes if you can to be sure. Make sure it's not connected as the hot on other devices. Does the 3-way switch on the right use the white wire somewhere? That's a clue.

Neutrals are required in switch boxes, but that's a very recent code update. It's equally likely you'll have to run your own neutral.

Traditional, non-electronic switches don't use a neutral because there's no load on a switch. All a switch does it connect or disconnect the circuit behind the switch; i.e: your light(s).

Electronic switches do take a neutral because they carry a load.
