2 way light switch not working correctly Electrical Advice

2 way light switch not working correctly Discussion Thread2 way light switch not working correctly Electrical Advice

Hi,
I replaced a 2 way light switch and seem to have issues.

For context, I have a hallway switch which is a 2 way and kitchen switch which is 2 way. I replaced the kitchen 2 way that operates both the kitchen and hallway lights. The kitchen lights work fine however there is an issue with the hall lights.

Please see two situations below.

Hallway switch On (Hall)
Cannot switch hallway light off from kitchen
Can only switch off from hall

Hallway switch On (kitchen)
Cannot switch hallway light off from hall
Can only switch off from kitchen

Seems the switches are working independently but not together

Attached is the original hallway/kitchen switch cables.

Would anyone be able to advise what the issue is ?

The terminals on existing are A com, A1 and A2 and B com, B1 and B2

The new switch has two lots of com, L1 and L2.

Original Wires

Thanks
Russell
