Slave light switches (not dimmer)

[gill557]

Hello, hope someone can advise. In my hall I have 4 gang 2 way light switch. One switch turns on 1st floor landing
On 1st floor landing I have 2 gang 2 way switch one turns on 1st floor landing and one turns on 2nd floor landing. I want a slave on 1st floor landing to turn on the hall light.
On 2nd floor landing I have 2 gang 2 way switch which turns on 2 x 2nd floor landing lights.
Do I need to replace all 3 switches? I've attached a diagram to make it simple to understand.
What manufacturer sells what I need?
I will get an electrician to fit, just need to know what to get
Thanks for any help

You will likely need an additional cable between the two switches plus of course an additional 'gang' on the first floor.

Perhaps if additional wiring is a problem, wire the hall switch through or disconnect it, and put a kinetic module in the hall ceiling and use stick-up kinetic switches to turn hall on and off from wherever.

Thanks, hadn't heard of kinetic modules. I don't want to add cables as whole house just been decorated.

It case you're looking for them it's spelled Quinetic. They work very well.
