3 position Spring return selector switch

[Anonymous]

Hello,

I am new to auto cad. I am trying to see how do i show the  wiring connection for 3 position spring return selector switch in autocad. 

I need my left contact as Forward Enable and my Right Contact as Reverse Enable. When it returns in the center its normally open contact.

Anybody can show me how do I show the wire connection in autocad Electrical ? Do i need more than 1 contact block to show this connection ?

Thank you

I have created some symbols which show all that sort of information as I to have trouble with the way ACADE does selector switches.

In the attached zip, I've included all versions of the Parents and Child blocks.

The files are for 2, 3 & 4 postitionswitches with a parent version of each and a child version of each to allow for any combination required.

To show the spring return, there should be a block in the icon menu to do so. It should be located under Qualifying Symbols -> Mechanical Controls.

The block names are formatted as *SS?_KN$P^^^.

* is for H (Horizontal) or V (Vertical)

? is 1 or 2 for Parent or Child.

$ is for the number of positions (2, 3 or 4)

Finally, the ^^^ show what positions are closed. Left (L) Right (R) Centre (C) or in the 4 position switches Centre Left (C1) and Centre Rights (C2).

Note that the solid square indicates the closed position/s on that particular contact.

Using the Kraus & Naimer brand of switches as well as the blocks I attached previously and Horizontal orientation for this so yours may vary depending on the brand and orientation of the wiring.

For the left position use a three position Left contact closed Parent block (HSS1_KN3PL) and place 1 & 2 in the terminal positions.

Navigate to the  Qualifying Symbols and then Mechanical Controls in the Icon Menu. Select and Insert the symbol for a '3 pole return to Centre switch' near the parent block.

Next you insert the child block (HSS2_KN3PR) for the right Position and place 3 & 4 in the terminal positions. Select the parent block to associate them together.

Finally, Edit the Parent block and place the desired Switch Position descriptions in the appropriate positions and allow it to update the child.

End result is something like this...

The blocks I use have provision for the linked line if so desired.

I'm not sure of your location but the general convention I use is the supply into the lower number and the switched output from the higher number.

So for this application, terminals 1 & 3 would have the supply and terminals 2 & 4 would have the switched outputs.

Be aware that some of the suppliers of these switches can insert internal links and external links so it is wise to physically check your particular switch for these before assigning terminal numbers.
