Light Switch wiring question

[TorqueDirty]

Hi folks,

Need an answer for what I hope is a simple question.

I have a room that is lit by GU10 spots.

I plan to replace the current halogen bulbs with dimmable LED GU10s and want to wire in an LED dimmer switch.

Here is my question:- There are 2 switches that operate the spots in this room. One is a single gang switch that controls only the lights for this room, and the other is part of a 2 gang switch that controls the lights for this room and another room.

Do I need to swap out both switches for LED dimmer switches or can I just replace the single gang switch and leave the other 2 gang switch alone. I get that I won't be able to dim from the standard 2 gang switch but that does not bother me as long as the other 1 gang LED dimmer switch works. Will this work or do I also need to wire in an LED dimmer switch for the second switch that controls the lights for this room?

Cheers
TD

You just need to replace the dimmer. At the end you want the dimmer.

Dimmer also needs to be the correct type for led
