Is a rotary dimmer or a push-button dimmer more convenient to use?

There are dimmers with potentiometers or detented steps for turning. They are wonderful to use. There are pushbuttons - with those you have to hold the contact for it to dim. Our rotary switches are pushbuttons. You have to hold the rotary switch at contact for it to dim. Always hitting it is a bit fiddly. This is the price to pay for aesthetics and haptics in this case. I just noticed it could use a cleaning again

hm... we even have both. For pressing looks more elegant, but you have to stick with it. Twisting looks more modest, but is turned quite quickly.

Rotary dimmer is more practical. We still decided on push-button dimmers. They look better and in my opinion, the operation is not that much more complicated. I think people won’t want to adjust the brightness differently every time anyway, but usually use the last saved setting.

It's not exactly an answer to the question. We have installed Philips Scene Switch. It has 3 dimming levels that are switched by turning on and off, and it saves the last setting. Usually, the darkest level is always activated in the living-dining area. This way, we have completely done without dimmers. There are now also many lamps that have dimming levels. Some save the last setting, others unfortunately do not. With a dimmer, you can of course dim continuously, depending on what you want.

Step switches are of course a compromise, but I personally find, for example, the continuously adjustable light sources significantly more pleasant.

Step switches are of course a compromise

That can be seen differently as well.

The less I have to "deal" with a switch, the more perfect I find it.
An individual, precise setting takes longer than just tapping on it
If many different settings are not needed, 2 or 3 can be enough – and then are found more quickly.
These are small differences, but that's what we're talking about anyway
