Does it make any sound as it switches on and off? It it uses a mechanical relay instead of a solid state switch it may click audibly.

Yes, it makes a fairly loud "click" sound when it switches on and off. I had to replace my 12 year old switch with a new one. Same brand. But this new one is much louder than the old one.

As the other response indicated, the sound is mechanical, not electronic, so it can't be turned off...but it is not particularly loud--it more sounds like the closing of the electrical contact than a deliberate click. I actually haven't used the keyboard all that much so far, but it seems pretty decent for the price.best wishes, Tom

No! it does not make any noise. But it does flash at night and may flash a low level single bulb in the daytime as a marker that something is in the field of view

There are slight clicking sounds when opening and closing it but I wouldn't consider it noisy.

Perhaps you have a bad unit. There is an audible click when it turns on but is otherwise silent.

I Put four of these fifteen minute twist timers in my home. they do make a slight clicking sound as they count down, but the fan motor is far louder then the clicking from the switch, when they time out and turn off the switch does make a little louder off click. I use these switches for for three bathrooms and one laundry room, and the slight sounds made by the switch are a fraction of the sound that the fans make. It doesn't bother our family. I hope this helps you. Jerry W., Moreno Valley, Ca.

It does not make any noise. The only indication (besides the visual display of the changed temperature setting) is the sound of the A?C or heat coming on.

If it beeps at all at any time I don't hear it. It's also tempermental at times when you're going from one time set to another. The last one of the same brand that I had ceased one of it's button functions and had to be returned,

Since this is a digital timer, I have not noticed it make any noise. The lights that are controlled by the timer make more noise turning on than you ever hear from the timer itself.

Mine does not hum, I use it as an automatic transfer switch in the living room, it's been on 24 hrs a day for a month with zero noise. I would return it and try another one.

Very quiet. The only time you will hear it is when it clicks on or clicks off.

It makes noise when you push it. The knobs make a noise when you turn it but it's just like a click. When you push it, it sounds like a motor running

This heater is very quiet but does make a clicking noise when it cycles on and off. I am a lite sleeper but after a little while I didn't even notice the noise. I hope this helps.

The only noise I will occasionally hear is a slight click when the power switches on/off. Other than that, it is completely silent. It's basically a digital clock with outlets

When you flip the actual on/off switch, it will click. Moving the heat settings will not make a clicking noise.

It does make a noise when it's turned on, which I would describe more as a loud click.
