Open and Closed Contacts

[Electron25]

I am new to visio and I have been playing around with electrical contacts.  I have found how you can change the contact for open to close.  Is there a tutorial out there that could show me how this is done?  I want to make a switch the when "switched" will change various contacts across the drawing.  I was looking at the dip switch tutorial but its a little complicated.  Is there a recommended reading or readings out there to build up my knowledge level in this area?

Thanks for your help.
