Question about Electrical Supplies
Hi i want to change the light switch in the hallway. it has two switches on one board. one is for downstairs and the other one is for upstairs hallway. there are two cables coming in to the same box. they each have red blue and green wire. i tried to connect looking at the old switch and only the downstair one works. on the switch there there is 3 holes at top and 3 at bottom. they are common and L1 and L2. the top had a wire which was a loop from common to L2 i think. which wires go where please
It sounds like you have what is called a three way switch for the upstairs light. This means that the light is controlled in two locations. The extra wire you refer to as a loop is called the traveller it goes between the two locations. You need to use the proper type of switch for 3 way applications. Once you get that there will be three holes instead of 2. the traveller usually installs in the hole that is alone (usually 2 holes on the bottom and one on the top). Any 3 way switch will come with instructions, or you should be able to find diagram easily on line.
