Touch wall switch
Replaces the plate itself. Choose it when the wall box can host the channels you need and you want local touch, app and voice on the same device.
Sourcing a wifi smart switch for a project usually starts with the wrong question. Start with the wall box instead: how many gangs does the plate need, is the cut-out a US standard size, and does the existing wiring include a neutral line? Each answer narrows the field, and every qualified path on this page ends at a model number with a stated per-gang load ceiling and a listed certification. If you are also weighing a smart light switch for app and voice control in that same box, the specification block below shows which limits apply before you commit to a quantity.
Four device families cover most lighting-control requests. Read the one-line definition, confirm it matches the job, then move straight to the verified specification block.
Replaces the plate itself. Choose it when the wall box can host the channels you need and you want local touch, app and voice on the same device.
Sits behind an existing switch plate. Choose it when the visible faceplate must stay as-is and only the control layer changes.
Adds brightness control. Choose it only after you have checked lamp compatibility and the minimum load a dimming circuit will tolerate.
Controls a plug-in load instead of a fixed lighting circuit. Choose it when no wiring change is permitted at all.
A single model covers the three-channel US job. These are the current, stated facts for that model — use them as the baseline before you compare anything else.
Why this one leads the page: three independent channels run three lamps or three lighting zones from one US wall box, with local touch, mobile app and voice control on the same device, and no hub in the chain. The front panel is tempered glass and the back shell is fire-retardant PC, with overload protection built in.

|---|---|---|---|---|---|---|---|---|---|
| PST-TY-U3 | 3-gang / 3-channel | US standard | AC 100–240V, 50/60 Hz | 10–400 W per gang | 5–200 W per gang | N+L (with neutral) / N+L & Only L (without neutral) | White / Black; Gold / Grey options | FCC, CE, RoHS | View PST-TY-U3 |
Load figures are stated per gang, not per switch. Plan each of the three channels against its own lamp wattage before you size a project.
Two wiring configurations are offered on this model: N+L with a neutral line present, and N+L & Only L for a box without one. That choice is the first thing to settle, because it decides the variant on the purchase order — not a generic "one size fits all" switch.
The second thing to settle is wattage. Each gang has its own ceiling, so a three-channel job is planned channel by channel, not as a single total. Confirm the lamp type on each circuit first, then read the matching ceiling below.
Certification claims belong to a specific model and a specific market. This SKU is a US standard switch, and that is the box type it is built for.
FCC appears in this model's certification list. Request the certificate copy alongside your quote before submitting it to a specifier.
CE and RoHS are both listed for PST-TY-U3. Note that the switch itself is a US standard unit — the listing is a compliance statement, not a claim of EU wall-box fit.
Tempered glass front panel, fire-retardant PC back shell and a compact profile sized for standard US electrical boxes — three channels share one box.
Do not specify this model for EU 86 mm or UK back boxes unless a corresponding verified model is quoted for that market. Confirm the destination standard on the enquiry and the correct unit will be proposed.
Four typical briefs, each tied to a stated product fact and the decision it forces.
Fact: three independent channels, three lamps or zones from a single US box.
Decision: use PST-TY-U3 when the three circuits share one box and each zone stays under the per-gang LED ceiling. If a fourth zone appears, split it onto a second switch instead of overloading a channel plan.
Fact: the model is offered as N+L or N+L & Only L.
Decision: inspect the box first. If no neutral reaches it, order the Only L configuration; do not assume the with-neutral unit can be adapted on site.
Fact: Tuya Smart / Smart Life, Amazon Alexa and Google Assistant, timers, scenes and grouped channels — no hub required.
Decision: specify it when you want dimmed-down pre-show scenes and independent channel scheduling driven from a phone rather than a separate control system.
Fact: FCC, CE and RoHS listed; tempered glass front, fire-retardant PC back; stated for offices and residential living areas.
Decision: request the catalog and certification documents with the quotation so the submittal package is complete in one pass.
