1 gang 3 way light switch wiring diagram - I've designated, pretty appreciably, why a twine manage system can be intricate in the article 2 way switch with 2 wire manipulate. All the troubles raised there observe right here too, specifically if utilized in stairways and the switches are on exceptional floors. Right here we've got a three way switching lighting circuit (now and again referred to as way switching with intermediate). This allows a unmarried light to be turned on or off from any of the switches. This page suggests it stressed in the old cable hues if your own home has the brand new colorings you want to go here:.

All earth wires ought to connect with the earth terminal inside the switch again-boxes and in case you are the usage of metallic switches there have to be a loop from this earth terminal to the one on the switch plate (see notice a on fig 2).
The circuit consists of a way transfer at each quit (pinnacle and bottom switches in fig 2) and an intermediate transfer in the center. All three switches are connected together through a 3 center and earth control cable. Word that the cord linked to the com terminals is looped straight via the intermediate transfer using a cable connector. All earth wires ought to connect with the earth terminal within the transfer back-containers and in case you are using steel switches there need to be a loop from this earth terminal to the only at the switch plate (see note a on fig 2).
