Lab 6:

Title: two lamps controlled from three different places by means of two three-way switch and by
one intermediate switches and will be able to do wiring of lighting point

Objective:

 Set up a system to control two lamps from three different locations using two three-way
switches and one intermediate switch.

Materials, tools and equipment are required:

 Solid copper wire  Slide cutting and combination pliers


 Lamp holder  Screw driver
 Incandescent lamp  Hammer
 Insulating tape  Multi meter
 Three way switch  Junction box, hack saw
 Four way switch  Tape rule and conduit
 Power source

Procedure:

1. Given the symbols and the indicated positioning in the figure we completed the layout
diagram.
2. After completing the lay-out diagram we got it checked by our instructor, after getting his
approval we proceeded to construct the wiring on the circuit board.
3. First we connected the two lamps to the three-way switches and the intermediate switch.
4. Then, installed the three-way switches at two different locations, such as at the top and
bottom of a staircase.
5. Intermediate switch is installed at a third location, such as at the entrance to a room.
6. Before we connect our circuit to a power source we made sure there is no short in our
circuit using multi meter.
7. Finally, we tested the setup by turning the lamps on and off from each of the three control
points.

Discussion and Results:

The use of three-way switches and an intermediate switch allowed for the lamps to be controlled
from multiple locations without the need for complex wiring or additional components. This
setup can be a cost-effective and efficient solution for applications that require lighting control
from multiple points.

The setup allowed for convenient control of the lamps from any of the three control points. The
lamps could be turned on or off from any of the three locations, demonstrating the functionality
of the system.

Conclusion:

The above experiment show the functionality of controlling two lamps from three different
locations using two three-way switches and one intermediate switch. This setup can be applied to
various real-world scenarios and can be a valuable addition to any electrical system that requires
lighting control from multiple points.
