You ever order something for a home electrical job and realize the product name tells you almost nothing unless you already speak the language? And that's exactly what happens with the efapel centro p/comando de 1 canal mono branco - 50700tbr. It looks like a random string of words and numbers — but if you're wiring up a switch or finishing a wall plate in Portugal or anywhere using European install standards, this little part matters more than it looks.
This changes depending on context. Keep that in mind.
I've installed enough of these to know the confusion is real. But that doesn't tell you why it's good, what it fits, or where people mess up. You see "centro p/comando de 1 canal mono branco" and think: what am I actually buying? Here's the short version — it's a single-channel switch mechanism and center piece from Efapel's Centro P range, white, with a specific reference number. So let's get into it.
What Is Efapel Centro P/Comando De 1 Canal Mono Branco - 50700tbr
Look, Efapel is a Portuguese brand. The Centro P system is their modular range of switches, sockets, and frames. If you've done electrical work in Europe, especially the Iberian market, you've probably seen their boxes stacked in a hardware store. It's designed so the internals — the "comandos" or mechanisms — snap into a base and then get covered by a plate Simple as that..
The efapel centro p/comando de 1 canal mono branco - 50700tbr is one specific piece in that system. Break the name down:
The "Comando De 1 Canal Mono" Part
This means it's a single-pole switch mechanism. One channel, mono (single), for controlling one circuit — like a light from one place. It's not a dimmer. It's not a two-way. It's the simplest on/off action you can get. And honestly, that's what most rooms actually need.
The "Centro P" System
Centro P is the modular platform. The mechanism (50700tbr) is built to sit inside Centro P supports and frames. You don't buy the cover plate with this — that's separate. The white finish is the standard bright white Efapel uses, which matches most of their Centro P frames Nothing fancy..
The "50700tbr" Reference
That's just Efapel's article code. If you're ordering from a distributor, this number is what cuts through all the confusing descriptions. Search the number, get the exact part. In practice, that reference saves you from ending up with a switch that doesn't clip into your frame The details matter here..
Why It Matters / Why People Care
Why does a tiny white switch mechanism matter? That's why because most people renovating a home or fixing a rental underestimate how annoying it is to mix systems. You buy a "white switch" from one brand and it doesn't fit the box you already have. Or the plate looks off because the white is a different shade And that's really what it comes down to..
The efapel centro p/comando de 1 canal mono branco - 50700tbr matters because it's a known, standardized part. Which means if your house already uses Centro P, this is the exact replacement. Practically speaking, no guessing. And if you're starting fresh, it's a cheap, reliable single switch that electricians trust.
Here's what goes wrong when people don't pay attention: they order "a 1-gang white switch" from a generic marketplace. Worth adding: or the rocker doesn't sit right in the Efapel frame they already bought. In practice, it shows up, and the mechanism is too deep for the flush box. Turns out, the small stuff like this is what turns a 20-minute job into a Saturday afternoon of returns.
Most guides skip this. Don't.
How It Works (or How to Do It)
Installing the efapel centro p/comando de 1 canal mono branco - 50700tbr isn't hard. But there's a right way, and then there's the way that leaves you with a wobbly plate It's one of those things that adds up..
Step 1: Confirm Your Box and Frame
Before anything, check that you've got a Centro P compatible support. The 50700tbr mechanism clips into the Centro P base (the part screwed into the wall box). If you're using a different Efapel line — like Centro I or another series — it won't seat properly. Worth knowing before you strip a wire Nothing fancy..
Step 2: Wire the Mechanism
This is a mono switch, so you've got two terminals typically: line in, line out to the load. Loosen the screws, strip about 9–10mm of copper, push in, tighten. Don't overstrip. I know it sounds simple — but I've seen people leave 2cm of bare wire hanging because they guessed. That's a fault waiting to happen.
Step 3: Clip Into the Base
Once wired, the mechanism pushes onto the Centro P support until it clicks. You'll feel it. If it's loose, it's not in. And here's the thing — a loose mechanism is the #1 reason plates look crooked later.
Step 4: Add the Rocker and Frame
The white rocker (sold separately or sometimes bundled depending on supplier) goes on the front. Then your Centro P frame covers the edges. Screw the frame to the support, not the mechanism. The mechanism stays clipped; the frame holds the look.
Step 5: Test
Flip it. If the light goes on and off without buzzing or warmth at the switch, you're done. If it feels stiff, the rocker might not be seated. Pop it off and press firmer.
Common Mistakes / What Most People Get Wrong
Real talk — most guides online treat all switches as interchangeable. They're not. Here's where people slip up with the efapel centro p/comando de 1 canal mono branco - 50700tbr:
Buying the mechanism thinking it includes the plate. It doesn't. The 50700tbr is the guts. You need the Centro P frame and rocker separately. I've made that mistake on a job once and drove back to the store cursing.
Assuming "mono" means anything else. Mono = single pole, one way. If you need to control a light from two spots (stairs, long hallway), this won't do it. You need a two-way comando. People buy the 50700tbr, wire it up, and wonder why the second switch does nothing.
Mixing finishes. Efapel white is close to standard but not identical to every "white" on the market. If you use a non-Centro P frame in "ivory white" next to this, the difference is visible. The short version is: keep the system consistent It's one of those things that adds up..
Over-tightening the frame screws. Cracks the plastic. Then the whole thing looks cheap even though the mechanism is fine. Snug is enough It's one of those things that adds up..
Ignoring the box depth. Centro P mechanisms are slim, but if your flush box is recessed too far, the frame won't sit flush. Use spacer rings or deeper boxes. Most people blame the switch. It's the wall Less friction, more output..
Practical Tips / What Actually Works
After years of small jobs and a few full rewires, here's what I'd tell a friend about the efapel centro p/comando de 1 canal mono branco - 50700tbr:
- Buy a few extra. They're cheap. If one mechanism clips wrong or a terminal cracks, you're not stopping work to order again.
- Keep the reference on your phone. 50700tbr. Type it in the distributor site. Don't search "white Efapel switch" — you'll get ten variants.
- Use proper Centro P frames. Even if a generic plate "looks like it fits," the clip tolerances are different. The real ones click and stay.
- Label your wires. Sounds basic. But when you're swapping a mono switch and the old one had three wires because someone bridged line, know what's what before you disconnect.
- Check the rocker style. Centro P has different rocker designs over the years. If you're matching existing, look at the old one. The mechanism is the same; the rocker shape changed slightly in some batches.
And one more — if you're doing a whole house, buy all
frames, rockers, and mechanisms from the same batch or supplier order. Efapel tweaks shades and moldings between production runs, and a half-degree of white difference across a hallway reads as a mistake once the sun hits it.
When to Call Someone Else
This is a low-voltage-risk part if you cut the breaker first, but "low risk" isn't "no risk.Think about it: that's not a 50700tbr job — that's an electrician job. Now, " If your box has aluminum wiring, burnt insulation, or more than three conductors with no clear line/load split, stop. Same if the wall is concrete and the box is floating because the anchors failed. Fix the structure before the switch.
Conclusion
The efapel centro p/comando de 1 canal mono branco - 50700tbr is about as straightforward as a switch gets — single pole, one channel, clean white, Centro P system. The part itself rarely fails. And what fails is the assumptions around it: wrong frame, wrong wiring expectation, mismatched finish, or a wall that wasn't ready. Buy the mechanism, the correct frame, and the rocker as a set, kill the power, seat it properly, and it'll outlast the paint job. Keep the reference number saved, keep spares on hand, and don't overthink a part that was designed to be simple Worth keeping that in mind..
