BN-LINK Heavy Duty 60-Minute in-Wall Spring Wound Countdown Timer Switch, Mechanical Switch Timer for Bathroom Fan, Lights, No Neutral Wire Required, 2 Wall Plate (White and Silver Metallic)

Muy útil este temporizador. Lo uso para activar una motobomba por periodos específicos y no tener que estar pendiente de apagarla.

Does the job so far. Appears to be good quality and installation was easy. It will be a tight fit in most electrical boxes however. I will update this review if the lifespan is prematurely short.

works great and easy to install - just 2 wires and take few min

Good physical size making it easy to install in a standard double-gang box with a light switch. There is no place to attach a ground to this timer. But the instructions say that the timer will cease to operate if power is lost and resume operation when power is returned. This is not true. This is a mechanical spring-driven timer mechanism that continues to run until it comes to the end with or without power.

We have a water pump on a switch in our shed that we keep locked. We put it on the switch so we don't leave it on all the time. But we found that we would forget the keys to the shed in the house some times. This was highly annoying. So we replaced the flip switch on the inside of the shed with this timer switch on the outside of the shed. Now we can turn it on and use the water for up to an hour without needing to add more time. And we don't have to worry about forgetting it in the on position. Since the shed is down the hill 200+ feet from the house, it is nice to know we don't need to worry about the pump being left on by mistake nor do we need the keys to the shed if all we need is water access.

This timer lasted one week. I always set it past 10 minutes and it fails 50 percent of the time. Its clicking but not counting down. It's been in use for 30 days and I can't send it back. Wasted $20.00.

Arrived on time. Product as described. Works perfectly and easy to install. It is a 60 minute mechanical timer. I prefer electronic ones but they always burn out…current surges. I have 2 similar timers in other bathrooms and they’re 10 years old and still work perfectly.

I had a fan with only two wires (black for power in, white for the power out feeding the light.) T he metal junction box was grounded. I tried various digital timers but without three wires plus a ground they could not be installed. You need a deep junction box for this timer as it is large and you need room for the wires. It is a right fit but it looks great and is very solid as installed. You just turn the sleek knob to turn on the fan and set the time, and the mechanical timer counts down and then it turns off. It worked so well, I bought a spare and put it in the garage as people always leave them on. This kind of timer is increasingly difficult to find. Note that it contains two sets of trim pieces - I used the white ones. Looks very sleek and modern like something from Nest or Apple actually.
