Light switches for bathroom - question re DP switch

Hello all

I am doing a like-for-like replacement of light switches in our home. Our bathroom has two switches - one for the ceiling lights and ventilation, and the other for LED lights around the cabinet mirror. The picture below shows the connections. One side is a simple 2 way module, the other is a double pole module.




I am looking to replace the above with the below switch modules. My question is - are the DP grid modules the same in both? The DP module for the current switch has N L(Load) and L(Supply) ports whereas the replacement show the ports as L1, L2, N1, N2. In which ports should the wires be connected to the new switch?

Thanks!!

Apart from L & N are on the opposite sides - yes.

The old two-way has a parking terminal for Neutral loop but it is not used.

So does the old one.

The same as the old one - if it works properly.

And dont forget your earth fly lead to back of switch

At one point building regulations required where you have a window in the room to be able to turn on fan without turning on the lights, one method was to use a double pole switch so you could have a second switch for just the fan, normally pneumatic push switch or use light switch, since the blue wires have brown sleeves this seems likely in your case.

But both new and old switches are the same, so no problem.

Brilliant - thanks all for the help!
