The switch mounting boxes, or enclosures are often recessed within a finished wall. Mounting height, visibility, and other design factors vary from country to country. Residential and commercial buildings usually have wall-mounted light switches to control lighting within a room. Switches for lighting may be in hand-held devices, moving vehicles, and buildings. Light switches are also found in flashlights, vehicles, and other devices. Manually operated on/off switches may be substituted by dimmer switches that allow controlling the brightness of lamps as well as turning them on or off, time-controlled switches, occupancy-sensing switches, and remotely controlled switches and dimmers.

Portable lamps such as table lamps may have a light switch mounted on the socket, base, or in-line with the cord. In electrical wiring, a light switch is a switch most commonly used to operate electric lights, permanently connected equipment, or electrical outlets. This "double gang" (two unit) installation uses non-metallic-sheathed cable and twist-on wire connectors. Shown here will be fastened to this recessed, non-metallic box, then a cover plate is installed. If you want to control lights from multiple switch locations (for example, at the top and bottom of the stairs) or in any other nonstandard layout, you need to shop around.Type of switch in electrical wiring Two decorator-style rocker switches and wiring (often called "Decora switches", after the trademarked Leviton switches ), as installed in the United States. More control options: Only a few companies offer smart switches and dimmers that work in three- and four-way configurations or have alternative button layouts.Wireless technology: Most of the smart switches and dimmers on our list use Wi-Fi, but we also consider models that use other wireless technologies, such as ClearConnect, Zigbee, and Z-Wave.None of the models we’ve tested currently support Matter or Thread, two wireless standards intended to increase compatibility and make the smart home work better (for a deeper dive, see our article about Matter). Some models can also tie in to Apple HomeKit, IFTTT (If This Then That, which lets you create your own smart-home rules, called “recipes”), or Samsung SmartThings.

Smart-home and voice integration: Most of the models on our list offer some type of voice control, with support for Amazon Alexa and Google Home being the standard.

We consider it a bonus if a model offers scheduling based on sunrise and sunset or the status of other devices, as well as scheduling for every day of the week or an Away Mode (for security that simulates occupancy by turning lights on and off randomly).

Scheduling: All smart switches and dimmers offer scheduling capabilities, so you can turn lights on and off at predetermined times of day.

One of these typically costs around $2 to $10 more than the standard in-wall smart switch.

Dimming: If you have a dimmable light, you need a smart dimmer.

The only downside is that the DN6HD requires that Wi-Fi bridge, but you can buy it as part of a starter kit that includes both the bridge and one dimmer and slightly reduces the cost. Leviton’s companion app is notably easy to use, allowing you to set up the switch and create Schedules and Scenes we especially like that you can control the light directly from the dashboard of the app without having to search for it first, as you do with some other dimmers. This Leviton smart dimmer is also compatible with more smart-home platforms than any of our other picks, and its support for installation in three-way configurations (with an add-on switch or dimmer) allows for more creative lighting-control scenarios. We like that the bridge and app allow you to mix and match non-neutral-wiring devices like this dimmer with other items in Leviton’s Decora line, such as switches and dimmers that do use a neutral wire, as well as other dimmers, in-wall outlets, and smart plugs. It communicates wirelessly with the $20 plug-in Decora Smart Wi-Fi Bridge, which lets you add and control up to 25 dimmers and switches using the My Leviton app.

The Leviton Decora Smart No-Neutral Dimmer DN6HD is the least expensive smart dimmer switch we’ve tested among those that don’t require connecting to a neutral wire. Compatible with: Amazon Alexa, Apple HomeKit, Google Home, IFTTT, Samsung SmartThings
