Dimmable to conventional light switch question

Buka

Hello,
I'd like to replace a dimmable switch with a normal one - I want to replace a single dimmable halogen bulb with a very bright LED one (we don't need dimmer there but need a brighter bulb so I don't want to buy LED dimmer + more expensive LED dimmable bulbs).
This switch is however a part of 3 rotary switches.. All three of them look exactly the same at the back - see below, however the right one is controlling 8 LED bulbs and is working as ON/OFF only, by rotating the knob (non-dimmable, at least both dimmable and non-dimmable bulbs don't show any change on rotation of the knob after they're on). The middle one is not connected to anything, it's the left one I'd like to change. It is "turn to switch, turn further to brighten" type switch. The current dimmer switch is also not suitable for a single LED bulb as the min wattage is 60W (see the pic, the link is at the bottom on the message)
Not being an expert here, I'm a bit at a loss how to change only one of the 3 and at the same time keep the rotating knob so that they still look the same at the front. Also I'm confused why all three of them look exactly the same at the back while one is used to dim and another - just on/off? Maybe there's a way to change "a mode" of this switch from "dimmable" to "conventional", then it would behave like the right one?
Also the new LED bulb would be only 10W or so - a lot less then the current halogen one.

Doesn't look like I can post the picture here, but it is at the LINK https postimg.org slash image slash zfja4h7tf

Thanks in advance!

You'll need to replace the whole switch.

The reason why one of the dimmers appears to be acting like an on/off is probably because the LEDs aren't dimmable.

Heedtheadvice

Ignore the fact that one is not used and one is not acting as a dimmer .....plus you just wish a switch for the third; so just replace the whole with a new three switch face (or two if you insist and make sure the other is isolated). Simple cheap meets you need and the front will match visually to design of your choice.
(Second thoughts if the middle is not used make sure it is isolated anyway!)

OP may or may not have the skills to change a light switch (though it IS a simple DIY job once you know how to do it safely) but why would they need to get their entire electrical system tested (other than to put more money in an electrician's pocket)?

One of the skills needed to change the light switch is knowing how to do it.

Reminds me of the invoice for repairing a telly:

Changing a faulty transistor...........................FOC
Knowing which transistor to change................£50

Of course and whilst OP might be unsure about why the dimmer switch they currently have is operating in the way it does, that doesn't mean they do not have the knowledge to actually change the switch, or the ability to research how its done (its not rocket science).

Thanks all!
I have actually tried dimmable bulbs too in the non-dimmable switch on the right (they were not dimming). Hence it was really strange to see the same backside. Separately, I was looking at some Varilight dimmable switches and they have several modes which made me think maybe my current ones also have another mode or it's easy to "bypass" the dimmer.
Also thanks for the warnings, I think I'll manage to install the new switches when I decide what to go for (or how to change existing ones).
