One Way & Two Ways Switch

A switch is a simple device that makes or breaks a circuit. A switch can perform mainly two functions- ON, by closing its contacts, or fully OFF, by opening its contacts. When contacts are closed, it creates a path for the current to flow, and vice-versa, an open contact will not allow the current to flow. In electrical wiring, switches are most commonly used to operate electric lights, permanently connected appliances or electrical outlets.

The most commonly available and used electrical switches in our homes is the one-way switch. But there also exists two-way switch, though not commonly used. In its working, the main difference between them is the number of contacts they each have. The one-way switch has two contacts and the two-way switch has three contacts. In a two-way switch, there are two, one-way switches combined in one. One of the terminals can be connected to either of the two, but not both at the same time.

The advantage of a two-way switch is the ability to control a single device from two separate locations. A convenient and apt use for them is for locations like stairways, a long corridor or a very large room. So, imagine, it is late at night and you are at the bottom of a stairway. You flip the switch ON to light up the stairs as you walk up. Once you have reached the top of the stairs, with a two-way switch you can simply flip the switch to put the stairway light OFF. The same goes for a long corridor or a large room with more than one entrances. The two-way switch is also super convenient to use as light switch, and possibly the ceiling fan, with the 2nd location accessible besides your bed. So, no trouble of getting out of your bed to operate these appliances.


So, whether you should opt for a one-way switch or a two-way switch is entirely your choice and needs. The one-way switch also called the single pole switch is effective in small rooms, and for domestic electrical appliances. And a two-way switch is apt for multi-door large rooms, stairways and long corridors. An easy switch to operate but a little complicated in installation.
