The switches in our house are too high. They are often used to turn light on/off, but occasionally for other things, also on and off but using other devices. For all it is, it does not work is not very pleasant.
The problem with this kind of thing that is very easy to change and usually do not get one to do it for you, or if you get paid much more than it should cost. If it’s so easy to do, why not learn by yourself?
To change the switch, take note that you should cut off electricity in the area where you will make the change to avoid any accidents.
