BN-LINK Bathroom Fan Timer Switch for Lights Exhaust Fan Heater, No Neutral

This is just a basic time switch for lights or fans or whatever. I have two of them that I use in the bathrooms to set the fan to run during showers. They remove a lot of the humid air to make the room more comfortable and not fog the mirrors. I have bought timers before for a different home. Got the idea when a real estate agent, while showing a home for sale, turned on the fan in the bathroom. Then, forgot to turn it off. After leaving the showing, the home was empty and the fan kept running. It overheated and started a fire which caused a lot of damage. The house then could not be sold for several months due to repairs. This happened in my neighborhood and caused me to get a timer. These seem to work fine. They turn a little hard, and really hard when reducing the time set. They are new, so will likely be easier over time. They seem to run very close to the time set. I set one for 20 minutes. I check it at 18 minutes to see if it was fairly accurate. Normally the time set is not critical, just making sure it does turn off. My test resulted in the time going off just 15 seconds short of 20 minutes. More than accurate enough. I am satisfied. BTW, the white color is really white, not cream like a prior brand I tried.

Works like it should. I am manually defrosting a Danby freezer/fridge because the default factory setting goes into defrost about every hour. This freezer is fighting itself with this amount of defrosting. I think the fridge is a bad design by Danby. I disconnected the compressor red wire off of the circuit board and then connected the BN-Link timer switch between the live black "L" WIRE and the red compressor wire. Now I control when the defrost cycle happens! Tick, Tick, Tick. Update: more for my own record of what I wired where. I rewired to heater defrost wire and live 110v wire so that power goes directly to the defrost bypassing circuit board. Now when I turn on timer defrost starts instantly. I also added a push button toggle switch to turn off compressor while defrosting and it is wired into a thermostat wire (short cut) since it is just a relay interrupt. The thermostat is a add on designed for a chest freezer so that i can control the temperature. It works and gets below zero no problem.

If you've ever used a digital timer switch and had it fail within months (as they are apt to do), come to the other side: mechanical spring-wound switches. This solid timer switch has little that can fail. As mentioned in other reviews, the unit is large and bulky. Even in my spacious one-gang box, I had to be creative to fit the wires. But, with timers, that's normal with these switches. But one thing I really didn't like: the protective plastic film requires you to remove the switch and the bolted faceplate to remove it. And the plastic is so tightly applied to the switch that it takes a long time to remove. I was wondering why the unit has stranded wires instead of the usual copper wires. Maybe all timer switches have stranded wires? In any case, I found them challenging to deal with. The operation is amazingly easy. Just turn the knob clockwise and let it go.

If you are tired of your bathroom fan running all day because someone forgot to flick the switch, or if you’re constantly battling mid-shower humidity, the BN-LINK 60-Minute Spring Wound Timer is the absolute hero of home hardware. Why this is a 5-Star Game Changer: The "Set and Forget" Magic: It’s so satisfying to just twist the dial to 15 or 30 minutes and walk away. No more guessing, no more wasted electricity, and the fan shuts off perfectly every single time. Old-School Reliability: Unlike digital timers that have confusing buttons or screens that eventually burn out, this mechanical spring-wound design is built like a tank. It has that classic "tick-tock" sound that lets you know it’s working, and it’ll probably outlast the house. The DIY Win (No Neutral Required): This is the best part. If you have an older home, you know the struggle of finding "neutral wires." This BN-LINK switch doesn't need one. I swapped my old toggle switch for this in under 10 minutes—it’s a direct replacement that anyone with a screwdriver can handle. Sleek & Clean Look: It comes with the wall plate and a nice, tactile knob. It looks professional and modern on the wall, fitting right in with the rest of my bathroom fixtures. Pro-Tip: If you’re using it for a high-moisture shower, set it for 20 minutes after you get out. It clears the steam perfectly and prevents that annoying mildew buildup on the ceiling. Final Verdict: This is a $15-20 fix that solves a $100 humidity problem. It’s quiet, durable, and dead-simple to install. If you have a bathroom fan, you need this switch. 10/10!

I was tired of replacing the failed electronic Woods timers on an annual basis, so replaced with these BN-Link timers. If you turn the timer past 10 minutes, it will work perfectly. They are easy to install, take less room in the electrical box than the other guys timers. No Neutral wire is required. Simply wire in circuit between your Line and Load and you are golden. For the price, I think they're a good value. I hope this helps you make your decision! I keep up with my reviews and will revisit this one should the need arise. I give these timers my Big-Foot “Stomp” of approval and 5 stars!

Great timer for bathroom fan. Easy to install and works great.

I'd say these have saved some money around our house. Enough to pay for themselves? I don't know. But they're great in households where some occupants were never trained by their parents to turn out the lights when they left the room. And they're otherwise practical for controlling bathroom exhaust fans.

This vintage style rotary timer was a great replacement for my two-wire light switch. I can now time my outdoor light for up to 60 minutes and then it will automatically shut off. The kit comes with both a black and a white dial panel. The only bad part is that you do hear the ticking noise if you are close to it while timing.

Works perfectly and was easy to install myself. All hardware is included and having replaceable face plates and knob is nice touch. The mechanism is easy to twist and works well. No issues so far!

Buena calidad, fácil montaje y funcional

Funciona excelente

This switch is a great addition to my bathroom. It is easy to set the timer for the exhaust fan, and it works perfectly without needing a neutral wire. It looks clean on the wall and functions exactly as expected every single time.

Bought for my rental so they can leave the fan on for a few minutes after the shower and prevent humidity. For us it works perfectly for what we wanted. You can choose from 0 to 60 minutes and it's great.
