What is 2-Way & 3-Way Switching Circuits?
Three-way switching or (Four-way circuits in the US) connection is used to control electrical appliances and equipment like fan, lighting points etc. from more than two places. The most common applications of this configuration is staircase wiring, hallway & corridor wiring, hostel wiring, hospital wiring, tunnel wiring, godown wiring etc. where a light bulb is controlled from two, three or even more places for ON and OFF operations.
Construction & Working of a 3-Way & 4-Way Switch
The 3-Way switch is also known as Single Pole Double Through (SPDT). The basic construction and working principle of 3-way switch is illustrated in (fig 1) below.
How to Control One Lamp From Three Places?
In fig 4, the wiring diagram shows how to control a light point from three different places by using two 2-way switches and an intermediate switch.
Three Way Switching to Control Light from Three Places in Staircase
The following wiring diagram shows how to control a light bulb from three different places using two 2-way (or 3-way) switches and an intermediate switch or 4-way switch.
Applications of 2-Way & Three Way Switching
It is used to control electrical equipment and appliances from two different locations
It is also used in staircase wiring connections where a light point can be controlled from two or more different places.
It is used in large area premises, rooms, halls having two or more entry and exit points.
The main purpose of 2-way & 3-way switching is to control an electrical appliance, device or equipment, especially light points from two places.
