Below is a figure showing the most often used residential electrical blueprint symbols.
“electrical” is used to include electrical, electronic, and communications systems covered by the National Electrical Code (NFPA 70). This publication also summarizes recommended drawing practices for electrical construction drawings. 1.1 Symbols Included This standard is limited to North American symbols for electrical wiring and equipment. Basic Electrical Symbols – Common Basic electrical symbols like earth electrode, cell, battery, source, ideal source, resister, variable resister, pre-set resister, attenuator, capacitor, antenna, diode LED, crystal are included here.

Electrical Blueprint Reading
The most commonly used electrical blueprint symbols including plug outlets, switches, lights and other special symbols such as door bells and smoke detectors are shown in the figure below.
Note: Explanations for common household electrical items such as three-way switches and switched duplex plug outlets are below the figure.
Notes:
Duplex Plug Outlet: A standard plug outlet with two sockets for plugs.
Split Duplex Plug Outlet: Typically used in kitchens or anywhere the loads on a given outlet will be high. The two sockets of the duplex outlet are on separate circuit breakers at the electrical panel. This decreases the likelihood of having two appliances which are plugged into the same outlet trip the circuit breaker.
Switched Duplex Plug Outlet: This outlet can be turned on and off with a switch. Often used for lamps.
Toggle Switch: A common light switch.
3-Way Switch: A bit confusing but this means there are two switches in the home to control the same item (typically a light or group of lights). For instance you may have two entrances to your living room and a switch at both entrances to turn the living room lights on. You'll need to use 3-way switches at both living room entrances for this electrical circuit to work. The term 3-way actually describes the inner workings of the physical switch which is different from a standard toggle switch.
4-Way Switch: As above with the three-way switch but here three switches will control typically a light or group of lights. If you had three entrances to a room, you may want a light switch at each entrance. For this circuit you will need to buy one four-way switch and two three-way switches.

Double Pole Switch: Typically used to switch outlets and appliances on 240 volt circuits.
Electrical and electronic symbols and what is the significance of these symbols
What is the significance of electrical symbols
Electrical symbols are used to simplify drafting and understand the drawing. Electrical symbols are certified throughout the industry. The addition of lines, dots, shading, letters and numbers gives special meaning to the symbol. To gain the ability to interpret drawings and their corresponding symbol meanings, we must learn the basic form of different symbols.

What are the most common circuit symbols and symbols in electronic circuits?
Power Sources
Resistors
Capacitor
Indicator
Mutual inductors
Diodes
Integrated circuit
Thyristors
By understanding the circuit symbol we can know how the circuit is connected together. The actual layout of the components is largely different from the circuit diagram. To create a circuit, we need a separate diagram showing the layout of the parts on a stripboard or printed circuit board.
