 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. In the other switch position it changes over so that COM is connected to L2. The design is a "break before make" type, such that the connection to the first terminal is disconnected before the connection to the new one is made.
