Yet another home wiring puzzle
A hall with top and bottom lights and top and bottom single switches.
When top switch is on, only top light is on. When bottom switch is on, both lights are on. Top light cannot be switched off with top switch. Any suggestions? I am reluctant to investigate further as it is a rental property. Regards |

There is a general philosophy that an electrical fault needs looking at sooner rather than later. |

Top switch is two way. Switched live to bottom light also goes to NC of top switch. NO of top switch is an always live wire. COM goes to top light. That would explain why the top lamp has a brief flicker off when switching the top switch with the bottom light on. Any other theories? Regards |

Yup, that then gives the landing light a choice of "on" or "same state as the hall light". That would explain why the top lamp has a brief flicker off when switching the top switch with the bottom light on. The switches are break before make, there would be a very brief interruption in power. Any other theories? That sounds seminally plausible and simple, so Occam's razor suggests is a good one to go with! Do you know which circuit the upstairs permanent live to the switch fed from? Since that will dictate what you can do easily from the current starting point. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

Maybe only the top light existed originally, and both switches are two-way so that either one can control the light. The hall light was added later, connected to one of the two wires joining the two-way switches. -- Dave W |

Top light cannot be switched off with top switch.Any suggestions?I am reluctant to investigate further as it is a rental property.Regards A wire is taken from the switched live at the hall switch to both the hall and landing lights. So when you turn on hall switch it provides power to both light fittings. This cannot be turned off using landing switch. The landing light also has a switched live from the landing switch to the landing light and can therefore independently turn on and off the landing light (provided there's no power from hall switch).
