The document discusses tools and materials used for making simple electrical gadgets, such as pliers, screwdrivers, wire strippers, and soldering equipment. It also provides examples of simple electrical gadgets like extension cords, lampshades, and doorbells. The document stresses the importance of safety practices when working with electricity, such as wearing protective equipment and avoiding overloading sockets.
2. LET’S BE INFORMED
This lesson will discuss the different
tools and materials used in constructing
simple electrical gadgets and their uses
are also identified. Proper safety and
health practices in making these
gadgets will be observed.
4. Tools and other materials are very important for making and
troubleshooting electrical gadgets.
The following are some of the basic tools and materials used in
making simple electrical gadgets:
1. Pliers, such as long nosed and side- cutting pliers, are used to hold,
bend, cut, and twist objects and wires.

12. 9. Male Plug is a device inserted in a socket to
make an electrical connection.
13. Simple Electrical Gadgets and their Uses
Anyone who is interested to construct simple
electrical devices may find it challenging and
worth the effort and experience. Reading about
electricity and electrical gadgets on magazines,
books, and the internet may help you to construct
these cool gadgets. Learning the skills is beneficial
as it prepares you to explore, discover, make
things, and be globally competitive.
14. Below are some examples of electrical gadgets you may
find interesting and easy to construct with their uses:
1. An extension cord is an
electrical gadget that is
longer than an ordinary
cord. It has a male plug at
one end and a receptacle
at the other. It is used to
accommodate extra
electrical devices needing
electric supply.
15. 2. A lampshade is a
type of fixture that
covers a light bulb to
diffuse emitted light.
This is usually placed
in the living room or
bedroom.
16. 3. A doorbell is a
device usually
placed at the door
that gives off a
reverberating
sound when
turned on.
17. Safety and Health Practices in Making Gadgets
Many accidents happen at work involving
electric shocks and burns. Faulty electrical wirings
can also lead to fires, injuries and must worst, loss
of life, equipment, and property.
This lesson will give you information on how
to reduce the risk and some reminders on basic
electrical safety and more secured working
practices.
18. Here are some safety rules to follow:
• Never run in the shop to avoid slipping, falling, or bumping into
others who are working with sharp tools.
• Wear face shield, goggles, or safety glasses while working.
• Never hold a project in your fingers. Use clamp, drill press vise, or
pliers to hold it.
• Do not attempt to operate a machine or gadget if you do not know
how to use it properly. Ask help or assistance from your parents or
teacher.
• Report untoward incidents like accident or injury to the proper
authority.
• All electrical equipment and installations must be checked and
maintained always to prevent accident.
19. • Provide enough sockets-outlets for equipment in use
and avoid overloading them to prevent fire.
• Provide an accessible switch with emergency OFF
button near a fixed equipment to cut off power in an
emergency.
• Keep all cords away from areas where water is
present.
• Make it a habit to turn off electric gadgets and
equipment when not in use.
• Never allow electric wires to run under carpets where
they cannot be seen because of tripping hazards.
20. •Pull the plug and not the cord from an
outlet.
•Make sure to work in a well-lighted area.
•Use gloves and appropriate safety
footwear when using electric tools.
•Keep cords away from heat, oil, and
sharp edges.
21. LET’S EXPLAIN
•What are the hand tools and materials that can
be used when working on an electrical gadget?
•When do we use extension cords?
•Why do we use lampshades?
•Why do we install doorbells in our houses?
•Give and explain the safety practices in doing
electrical gadgets.
22. LET’S REMEMBER
• Tools and materials in making simple gadgets must be
identified to understand their functions better.
• Always observe strictly safety and health practices
while at work.
• Use appropriate tools, materials, and PPE (Personal
Protective Equipment) while working.
• Make sure that tools and equipment are kept clean,
properly maintained, and stored in a safe place.
