Hi All I'm pretty much the electrical amateur here. I installed a dimmer switch for an outdoor light, and it works great. I thought I'd do the same for the bathroom as well so bought some LED dimmable lightbulbs. However, when I removed the switch, there were more wires than I was expecting. The switch has a red top to it and I've come to realise it is a dual switch in one - controlling both lights and fan that does a boost when in use. Is there any way to replace this with my dimmer switch or a different kind of dimmer? I'm not sure what keywords to even search for... Current switch looks like this, but without the fuse: [URL]https://www.amazon.co.uk/MK-Switched-Fused-Connection-Outlet/dp/B00NJSW7EC/ref=sr_1_154?s=diy&ie=UTF8&qid=1542217073&sr=1-154&keywords=dp+switch[/URL] Thanks in advance!
