In a one-way switch, L1 is the only output terminal, meaning the switch simply breaks or completes the circuit. In a two-way switch setup, L1 works in conjunction with L2 to allow control from two different locations.

This one has thrown me a bit, as it is labelled differently to the others. The new switch (a BG Electrical Nexus 812-01) is on the left and the old one (of unknown manufacture) is on the right. How do I wire the new switch? Do I just put both 1 wires into L1 and both 2 wires into L2? Should I also put the brown wires into common? When it comes to wiring a light switch, it is important to understand the basics of how to wire the switch correctly.
The first step in understanding the proper wiring of a light switch is to identify the switch's parts: the L1 and L2 terminals, and the common (Com) terminal. Just replacing the pull switch in the bathroom that switches on/off the single light fitting. The switch has only L1 and L2 terminals (L3 is 'dummy' with no connection).
