BN-LINK Heavy Duty 60-Minute in-Wall Spring Wound Countdown Timer Switch for Lights, Mechanical Switch Timer for Bathroom Exhaust Fan, No Neutral Required, Wall Plate Included, ETL Listed, 1 Pack

Sound of the bath fan covers the timer ticking. Much easier than trying to get the family to remember ta "turn off that dang fan!"

Timer was easy to install. We had a dual faceplate with separate paddle switches for the bathroom light and fan. I was able to install the timer using the existing faceplate since the timer fit in the space used by the paddle switch. it was a tight fit getting the timer into the electrical box but it worked. Now we don't have to remember to go back and turn off the fan, the timer does it for us.

I really like my timer. When I stink up the bathroom, I can set the exhaust fan and just leave. I don’t have to worry the fan will run a long time, because it shuts off at whatever time you set. Thus, I don’t have to remember to turn it off.

This is the second time in 12 years heavy use that I've had to replace this clockwork timer switch. The original lasted 8 years; it's replacement's spring failed after 4 years. This unit fits as before BUT NOTE - The threaded shaft that holds the little faceplate is too short to engage the [nylon] retaining washer. So, I'm relying on the snug-fitting knob to keep things together. So far, so good, full function. PS - the ticking of the clockwork motor is much quieter in this switch than in the replacement unit I just replaced.

Over a year later and this timer still works perfectly. It is mounted on an outside wall in a junction box with cover, certainly not the best conditions but it never fails....not yet anyway. I use one for my RO system and one for a fountain on my patio. I have used others and rarely do they last longer than 6 months before sticking on. The dial on these remain firm and shut off consistently.

My sister-in-law has used these for a while to operate 12V and 24V DC fans in her off-grid home, so I picked one up also to control a strangely-designed bathroom fan that runs low voltage DC (from an internal PSU) down its switch legs for lighting & fan control. That's a big compatibility problem timers that need 120VAC to run, but not for simple clockwork mechanical designs like this one. If you do use one on DC, as with any mechanical switch, to avoid a shortened service life, the contacts should be de-rated to account for DC arcs causing more wear (no zero-crossing to quickly cut them off). Anything up to 3A should be fine, maybe a little more. In my case, that weird fan combo only sends down a 5V control signal at a few mA, so there should be essentially zero electrical stress, only mechanical wear. Hopefully the mechanism will last a long time. Like others have mentioned, the in-wall portion is physically large and needs a lot of width and depth, and so may not fit into all boxes. It makes a tick-tock sound while counting down, like an old fashioned wind-up clock but faster. While it's not terribly loud, some might find the sound objectionable, especially in quieter settings, like the bathroom off a master bedroom where someone might be trying to sleep. If you manually turn off the load early by twisting the dial fully counterclockwise, power is cut off immediately, but the ticking can take another minute or so to stop.

Bought 3 1 failed a few weeks in. The second just quit 2 months later. They need to be taken apart and a light oil sprayed in the gears. Not wd40 oil. Something like Kroll or gun oil in spray form. The switch itself is good. The timer is assembled dry

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.
