Explain how these lights are wired

[RobTi]

Hi I have a single light switch in my hall which works the single light above it and I have a double switch at the bottom of the stairs which worked the stair lights but the second switch works the upstairs hall light. Now I dropped a new 3 and e from the pendant to the light switch and wired this as brown- live, grey- neutral, black switched live and marked them up. Now the old 2 and e has the red into com on this switch. Wiring is old blue and new switch wire black red tape - L2, new live-brown & old yellow L1, lights work as they should, first photo hall switch, other two of the bottom stair switch, just want to understand how they work

All the wires are live (line). None is a neutral.

Thanks will that still be the same for the 2 lamps as it’s not 2 way in the strict sense as I can’t control the downstairs lights from upstairs but can control upstairs from downstairs

One of your switches is wired for two way operation, the other is just a single switch for the downstairs light. You should be able to work out which is which from the information that has been given.

Your wire connections to the switch terminals look very poor.

The wire should be under the screw, not along side it.

You should strip a few extra millimetres of insulation off the wires, and fold the ends over double, so there is more copper for the screw to grip to.

Not my wiring council switch and yes I always fold over the ends unless there is no room

Thanks everyone for the help I am going to try trimming the lip of the back box tomorrow as that seems the easiest to try first and see how the faceplates fit.
Thanks again
