The three terminals are usually named com l1 and l2 but sometimes com 1 way and 2 way are also used. These are often used on a stair case large room with switches by each door. 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. It is a standard single pole switch with three terminals.
