No, the neutral is only needed at the load. This is where the connection is made to the light fixture.
Electrically there is no reason you couldn't if the neutral exists in the switch box. But in a home, a switch is required just inside every door. So other arrangements would have to be made for that. Replacing a switch with a receptacle would mean there is no longer a switch, of course, for the lights. They would either be on all the time or off all the time. If you need a receptacle at this location, consider installing a combination unit with a switch and single receptacle on the same yoke.
you probably can't, you need a neutral and a live wire to make a fan work. switches normally only have live wires.
You need to first determine where wires go. If you Google 3 Way Switch you can get a diagram. Each switch has 3 contacts.. Think about a kids teeter totter. Each end represents a switch contact and the center is a common point. You connect the ends to either end on the 2nd switch. The common contact on one switch goes to supply power hot side and on the other switch the common point goes to the load. Then the neutral of supply connects to the load neutral and the supply ground connects to the ground of the load.
You will need a receptacle that you can wire each outlet separately (not jumpered). You would then wire the switch in series on the line conductor with the outlet you want switchable. Wire the other outlet directly to the power source. You can jumper the neutral from one outlet to the other.
You may need to first switch it on before off.
Unless the switch has a pilot light on it there is need for a neutral connection to the switch.
To bypass the cars neutral safety switch, you need to find the two wires to the safety switch and connect them together. It can also be done by putting the car in neutral.
To install a light switch without a neutral wire, you can use a switch that does not require a neutral connection, such as a mechanical switch or a wireless smart switch. These types of switches do not need a neutral wire to function properly. Make sure to follow the manufacturer's instructions carefully when installing the switch to ensure it is done safely and correctly.
Need to replace the neutral safety switch, or may just need adjusted.
To install a light switch that does not require a neutral wire, you can use a switch that is designed to work without one, such as a wireless or battery-powered switch. These switches use alternative methods to power the switch and control the light without needing a neutral wire. Simply follow the manufacturer's instructions for installation to set up the switch without the need for a neutral wire.
A neutral safety switch prevents the car from being started in gear which can make start moving unexpectedly. If you need to replace the switch, it's likely that it is broken. Switches usually go bad from corrosion.
If the neutral light is not coming on and the electric start is not working, it could indicate an issue with the neutral safety switch or the electrical system. Check the wiring connections to the neutral safety switch and the battery, and test the switch itself for continuity. If the switch is faulty, it may need to be replaced.
The neutral safety switch is located on the transmission shift lever. Its held onto the transmission case by 2 bolts in slotted holes. You will need to remove the kick down lever. The switch will slip off the shift lever with just a little pry if dirty. Replace the switch while the transmission is in neutral. There is a small hole in the side of the switch to stick a small pin or awl into to locate the neutral position of the switch. I would try to adjust the old switch before replacing it.
If the neutral safety switch is only working intermittently, some of the screws may be loose or the switch may have gone out of alignment. You can use a 12-volt test light to check the switch. If there isn't any power running through the wiring, you will need to replace the switch.
Need to know if it is standard or automatic and why.
It depends on the circuit used, but usually, yes.
If only two wires are available for the circuit and the switch requires a neutral wire, you may need to run a new wire that includes a neutral to properly install the switch. It is important to ensure all wiring is done in accordance with local electrical codes to maintain safety. If unsure, consult a licensed electrician for assistance.
