    Feel free to facepalm before answering this :)

    Replacing a pull switch for shower/extractor in my bathroom. I've killed the power, taken it down, made the diagram, identified from my main fusebox that I need 6A replacement....now I need to know the difference between 1 way and 2 way, so that I can buy the correct pull switch.

    Am I right in assuming that:

    1 way - wires from ceiling terminate in the pull switch - they don't go back into the ceiling and onto other switches

    2 way - wires come in from ceiling, into pull switch COM and L1, and then back out to other switches.

    My pull switch has:

    Yellow/Green cable earthed to a connector on the back of the plate

    Brown cable connected to COM

    Blue cable (in brown sheathing) connected to L1

    The cables all terminate in this switch, they do not go anywhere else.

    Hope that someone can advise!

    Thanks in advance

    edit: the pull switch controls the extractor fan, not sure what else i need to consider for this

    makes no difference which you have. (for your aplication)

    1 way is just that , 2 way can be used as one way or two way. more info is in the "sticky"

    2 way switching may also terminate at the switch depending on which wiring method and which end the switch is..
    check the WIKI for common wiring methods..

    Tapir--your "understanding" is not correct.
    One way is a simple on/off switch whilst a two way switch can be interconnected with another on a light controlled from 2 different switches, (eg bedroom wall and overbed pull cord)
    A two way switch can be used in a place that a one way would suffice, but not vice versa, so as Breezer says, for your case it is not critical. The price differences are negligible.

    Thanks for the advice Breezer, ColJack and TonyW2 - one new light switch fixed in place and working, no burnt fingers or house with no power :)

    I'd agree it's not full, but it's not completely wrong - with 2 way switching conductors do run from one switch to another...
