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.

​

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.

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.

​

3. A doorbell is a device usually placed at the door that gives off a reverberating sound when turned on.

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.

​

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.

​

• 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.

​

• 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.

​

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.

​

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.
