In the past I have done a transient analysis with Electronic Workbench of an RC circuit with a simple 2 position switch. Using Multisim 12, I can't open or close the switch once the simulation starts. I was able to do it with EWB. Am I missing something?

Hi Howard,
I don't have EWB 5 installed and can't verify the behavior but in Multisim 12, you cannot toggle the interactive switch in Transient Analysis. You should use the Time Delay switch instead

Hi Tien,
The time delay switch worked, but I found it more interesting when showing it to a class to be able to toggle. It seems that if you wire the switch to be closed, and then want to show an example where the switch is initially open and then closes, you need to re-wire the switch. Such is "progress" I guess.
As long as I have your attention, here are two other questions related to duplicating what I've previously done with EWB:
(1) Can you tell the schematic to display the node numbers? Otherwise you need to look at the parameters for each wire.
(2) I have simple examples from EWB with subcircuit blocks connected together. When I create subcircuits with Multisim, I don't see how to define the external connections, so that you can place wires from one to another (or to other components).

Hi Howard,
Another method to create a sub-circuit is select Place>>New Sub-circuit, enter the sub-circuit name then place the rectangle on the workspace. To build the circuit inside the block, double-click then "Open subsheet". The connector to communicate with the main page is under Place>>Connector>>Hierarchical connectors.
