What does a 2 way light switch look like?

Two Way Switches A Two Way light switch is a simple single pole “changeover” switch with three terminals. These are typically labelled COM, L1, and L2 (Some may label the L1 and L2 positions as “1 Way” and “2 Way”). In one switch position the COM terminal is connected to L1.

How do I add a second light switch without wiring?
