    I have wired this up so to control downstairs light. I have an intermediate by front door and a second switch further in that connects to light. On the landing I have a switch that runs to the intermediate switch.

    If I switch the landing switch off I cannot switch on or off with either down stairs. If the landing switch is in other position I can use both switches downstairs. I double and triple checked my wiring and cant see an issue.

    Any idea? help!

    two-way-plus-inter.jpg Standard wiring, how does your wiring match up? With electronic switches it is different, and if you are missing wires there are some kinetic switches which can get away without wires, but photos are good, with a photo of switches some one may see the error.

    Landing switch faulty or not wired correctly.

    That's what I'm thinking but I have checked the wiring diagram and its all correct.

    There is always the possibility that the copper core of one of the wires has snapped near the end, in which case it will feel very floppy.

    It is difficult to advise as there are two ways of wiring two-way switching.

    You could always disconnect the landing switch and put the two wires NOT in COM in two terminal blocks, then connect the COM wire to ONE of them, see if everything else works.
    If it does, connect the COM wire to the other block and see if everything else works.
    If it also does, then the switch is faulty.

    If one of the ways does not work, then something else is wrong.
