In the above instructions you describe a two way switch - 2 terminals at the bottom and one at the top. My existing light switch has those terminals but only two wires - red & Black (which has a little red cable sleeve moving up and down it). I have bought a one way dimmer switch with an earth and L2 terminal. Can I put the black wire into the earth and red into L2? Or do I need to buy another switch?
Thanks in advance!
