Two way light switch with 2 cores!

[ALH1976]

So i have a Ceiling Fan (lets just class it as a Light with a Pull cord at the light) and a light switch

Problem is i turn the light off at the Light at night .. and when i wake up i turn it on at the light switch.
Sadly the light switch is TWO Core so it doesnt really effect the light , ONE switch is on then the light is on, and other light switch will not turn off

So thinking of a Relay to change the 1P2T on-off switch in to a 1P2T on-on, not sure on what relay to use if i would have to drop the voltage down (making it even more complex) to send a signal to the relay via the LIGHT SWITCH.

also not looked in to the Light Switch at the Ceiling, just hope its a 1P2T on-on


Sorry for the Relay switch icon best i could do on this APP

It's not very clear what you're saying, so can you clarify:

You have a ceiling fan with an integral light.
It also has an integral (pull-cord?) switch to operate said light.
There is also a separate wall switch.
When either of the switches are in the closed position, the light will come on.
Both switches must be open to switch the light off.

You would like to change this switching arrangement so that it works as a proper 2-way switching arrangement.

Is any of the above correct?

yes basically

The problem is i would sooner do it without having to Rewire for 4 core (3+CPC)
why i was thinking of the Relay/Conntactors

What about kenetic type switches?

I’m sure one could be built into the pull cords, and another in place of the room switch… and the relay in the fan base somehow or ceiling void?

I think it should work, there's no obvious reason why it wouldn't. Might need a second relay for the switch at the light though, as I'd assume it would be a one way switch.

Something like this?

Never seems to have caught on in the UK, but you can have as many switches as you like on a single T&E , common to all switches, to control a single light, if you use an impulse relay and retractive switches.

In addition to Brians post above you can get electronic impulse relays, so no thud as they switch in and out.
