Problem Replacing old Dimmer Switch with new ordinary Switch

Anyone help, please?

The current dimmer switch is part of a 2-way setup in the dining room with an ordinary switch at the other side of the house.
The old dimmer switch has these terminals:

Loop - empty
Line 2 - black wire
Line 1 - red wire
Load - 2 red wires

The ordinary switch that I want to put in its place has these terminals:
Common
2 way
1 way

Can anyone tell me how to wire the new switch? Thanks very much!!!
