Installing a double light switch with dimmer

[wiktor520]

Hello, I am trying to switch a double light switch into a switch with one dimmer. The switch with the dimmer doesn’t have COM and L1 connections, but two identical and unmarked yellow cables. Am I ok to connect the two existing COM cables with any of the two yellow cables? And the other one with the L1 cable?

Any help will be greatly appreciated.
Many thanks

Most probably yes. Where did you get it from it looks a right piece of tat, doesn't even have a makers name on it.

And the back box looks quite shallow too

I ve never seen a new switch that came with the wires attached

Typical in the US but I would seriously doubt it's quality especially with two yellow conductors.
