My girlfriend bought an old apartment in NYC and we are trying to replace one of the dimmers with a standard switch. The 2 gang consist of the dimmer (Controls the living room lights) and a standard switch (Controls the kitchen light). A quick Google search told me the dimmer was causing flickering with the new led gu10 lights we bought from Ikea. We tried these lights elsewhere and they did not flicker.
When I went to open up the outlet it looked like there was only one power source split between the two? I am following mostly online guides and they all tell me to just attach either two black cables to the new switch or a red and black to it but it doesn't look like the case for my situation.
Is this out of my limited technical skills and we should call an electrician?
I have attached pictures below to show what I mean.
