Various electrical touch two-way light switch from  https://www.remote-control-switch.com Generally speaking, two-way switch controls one light from two locations: for example, the long hallway could have a switch at each end to control one hall light. Or a large family room that has two entrances could have a switch at both entrances to operate one overhead light. A two-way switch allows you to turn on the light conveniently when you enter an area rather than stumble through the dark to find the switch. Now we are going to talk about the difference between traditional two-way light switch and new electrical touch two-way switch. First of all, let’s see what are traditional two-way switch and new touch two-way switch. Traditional two-way switch has a single pole double throw configuration (SPDT). Each has a common terminal (COM) with a pole that can be switched between position L1 or L2. As diagram below shows, the live wire is connected to Switch1, and flow to the lamp through L1

Switches are classified according to the arrangement of their contacts in electronics. Electricians installing building wiring use different nomenclature, such as "one-way", "two-way", "three-way" and "four-way" switches, which have different meanings in North American and British cultural regions. If we say one-way switch in British cultural regions, it will be described as two-way switch in North American regions; and two-way switch will be described as three way switch and so forth. As a result, sometimes people will make misunderstanding about them. For example, people from USA say two-way light switch actually is called one-way light switch in UK. And if they don’t know the reason, they will get into a fight. Table below is to distinguish the difference between them. (Pole means separate circuit which are controlled by a switch. Throws means separate position that the switch can adopt.)
