Does a light switch require a neutral. You can replace a single-pole switch with a timer switch with no neutral connection based on the. Yes there are a few read very very very few switches that dont require a neutral but those will limit you to incandescent only. This is true even when you have a smart light switch in the off position.

To HAVE a neutral we want the line voltage to come to our switch box first. You will need to get a neutral wire at the switch in order to correctly wire and power the device. You can also have an electrician rewire the switch and light fixture which is potentially more expensive.

With non-metallic cable you have a black wire a white wire and a bare wire for ground. This does require that you have three wires at the junction box plus an earth. For the vast majority of the smart light switches they do need a neutral wire as the pre-requisite to function.

There will be a neutral on the circuit somewhere but its quite often at the light fixture in older homes. The most common requirement of any hardwired automated light switch is a neutral wire. For those based in UK Europe I found 2 x types ZIGBEE switches which do not require NEUTRAL wire and they are not dimmers only onoff and work perfect with smarthings and or directly with phillips hue links below.

Well youre in the right place. The most important consideration is the necessity of a neutral wire. Then from the switch box another loop goes out to the load light bulb or whatever.

When the switch is closed the Switched Live cable is live and powers the light bulb this allows current to flow from Live through the light bulb and to Neutral - making the light bulb turn on. Up until just a few years ago the neutral was not required at a switch location.

Switch boxes on the other hand dont need a neutral because they are just an interrupt spliced into the circuit. And this is why you can typically put an in wall micro at the fixture as another alternative.

Some motion sensing switches require that there be a neutral white wire attached to them some do notfor those that do there is no substitute. The neutral wire is use to provide power to the light switch timer for the clock. It remains has power when the switch is in the On Mode.

If you only have two wires at the switch you have a switched live type circuit. Of course there are standard light switches that will use a neutral wire. Now at CES 2020 GE Lighting has another batch of new products including new smaller-size smart light switches that dont require a neutral wire -- potentially a pretty helpful option for homes.

Power runs to the switch box through a neutral wire and it is then passed on to the lighting fixture. When the switch is open no current can flow and the light bulb is off. A standard switch loop consisted of the hot feed to the switch the switched return leg and a ground wire.

For these lights the switch box is where a neutral wire will be connected. However you will be glad to know that there are few smart switches I have reviewed below that dont demand a neutral wire connection attached and can work without it. The neutral wire allows the completion of the circuit and the switch to have power even when its turned to the off position when you want the lights off.

The neutral wire allows the circuit to be completed and the switch to be powered on. If you want to use smart switches and dont have a neutral wire in your switch box you can hire an electrician to run a neutral wire between the light fixture and the switch. In the case of smart light switches they typically require a neutral wire because they need to be powered all the time.

Without this neutral wire in place the circuit is broken any time the switch is now in the off position. In some cases a timer switch may require installation where only the hot leads are switched.
