Symbols can be inserted in text using one of the following methods: In the In-Place Text Editor, right-click and click Symbol. Simply place the cursor where you want the symbol to appear. Those tools automatically display when you create or double-click on mtext objects as well as dimensions, leaders, and tables that use multiline text.
One of the easiest ways to add the diameter symbol to your AutoCAD drawing is to select the Text Editor ribbon tab or right-click menu. You can use them to create repeated content, such as drawing symbols, common components, and standard details. For this circuit you will need to buy one four-way switch and two three-way switches.ĭouble Pole Switch: Typically used to switch outlets and appliances on 240 volt circuits.To insert the following text symbols, click Symbol on the expanded Text Formatting toolbar or enter the appropriate Unicode string: These text symbols are available in the following True Type (TTF) and SHX fonts: Simplex* Romans* gdt* amgdt* Isocp Isocp2 Isocp3 Isoct Isoct2 Isoct3 Isocpeur (TTF only)* Isocpeur italic (TTF only) Isocteur (TTF only)CAD blocks are named groups of objects that act as a single 2D or 3D object. If you had three entrances to a room, you may want a light switch at each entrance. The term 3-way actually describes the inner workings of the physical switch which is different from a standard toggle switch.Ĥ-Way Switch: As above with the three-way switch but here three switches will control typically a light or group of lights. You'll need to use 3-way switches at both living room entrances for this electrical circuit to work. For instance you may have two entrances to your living room and a switch at both entrances to turn the living room lights on. Often used for lamps.ģ-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). 
Switched Duplex Plug Outlet: This outlet can be turned on and off with a switch. This decreases the likelihood of having two appliances which are plugged into the same outlet trip the circuit breaker.
The two sockets of the duplex outlet are on separate circuit breakers at the electrical panel.
Split Duplex Plug Outlet: Typically used in kitchens or anywhere the loads on a given outlet will be high. Notes:ĭuplex Plug Outlet: A standard plug outlet with two sockets for plugs. Note: Explanations for common household electrical items such as three-way switches and switched duplex plug outlets are below the figure. 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. Below is a figure showing the most often used residential electrical blueprint symbols.įor other residential symbols, see our Blueprint Symbols page.
