Swapping 2 way dimmer for 2 way switch, please

[Smckent]

I am looking to swap a 2 way dimmer switch for a 2 way light switch and the wire markings are not the same. Can you advise please?

The current dimmer connections are Yellow to L1, Blue to L2 and Red in the middle to ~with line through it.
Options on the new switch are 1 way, 2 way and Com.
It's a standard room lighting circuit with 2 wall lights. This switch is by the bed, the 'main' 2 way switch is by the door.
I have photos of the wiring for both current switches and the back of the new switch. Thank you

Red to "com". The other two either way. There should (must) also be an earth wire to those faceplates.

As has been said the 1way & 2way connections are the L1 & L2
and the Com is the ~ terminal..

But MORE important.. You need to get a CPC (earth) connection onto those metal faceplates...
or if the cables do not have an earth wire, you need to swap them out for plastic switches...!!!

The earth terminal is essential for safe operation of the switch, not an optional terminal that can be ignored!

The new switch should have had a bit of paper with it, giving wiring instructions and some wording such as
"This accessory must be earthed"
