This is because two way switches can also be used on one way circuits. If you’re wiring a mains supply into each LED driver individually it would be classed as parallel wiring and can be done using the loop in, loop out technique. Using the recommended Lutron control cable which has two pairs of cables, one pair is for power and the other pair is for signal. Learn more. If you’re attempting to wire anything more complicated like upgrading a 4 gang light switch to a 4 gang dimmer switch it may be worth taking a quick photo first just in-case you get muddled up with the wires and need to revert back. The receiver is positioned in the ceiling void near to the lights. Light switches are functional items, and many of the basic varieties (made from white plastic) can look a bit plain. Sometimes called a crossover switch for obvious reasons.. Typically, these terminals will be marked COM and L1 (sometimes L1 and L2). This is an overview of how to wire a one-gang light switch on a one-way circuit: Switched Live Wire (SW) connects to L1 port Common Live Wire … Or you could change an existing switch to give you convenient, multi-way control of a light in your hallway, landing or stairwell. If you're replacing existing downlights you'll want your new ones to have a similar hole cut out size otherwise you'll either need to make the holes bigger or make them smaller (yes I said smaller) which would involve re-plastering your ceiling and re-cutting the holes. You could either have something simple like Scene 1, Scene 2 etc or try something more adventurous like 'All On', 'TV Watching', 'Party Time', 'Reading' and 'All Off' like in my example.
