Simulating Switching Circuits? SOLVED

Forgive me for being a noob, not that familiar with PSPICE type software, but how do I simulate a circuit that has, for example a SPST NO switch? I don't understand how to use the simulator to show when a circuit has the switch open or closed.

BTW... Great software. I hope to design a lot of digital circuits here.

Double-click the switch. You can change the State from "open" to "closed"

You can also use a time controlled switch element, and set the T parameter (switch time). In a time domain simulation the switch will switch states at the specified time.

Hi there,

Can a switch be opened/closed while simulating? Going back to build just to change a switch is not very intuitive.

Just wondering if it is possible to simulate bounce? I am playing around with some debouncing circuits.

You could use a PWS() or PWL() source.

For an example of a bouncy sort of signal see the PWS() source in:

For help in using PWS() and PWL() sources, see also:

Sorry, should have said: you then use the PWS() or PWL() source to drive the voltage controlled switch element.

Is good yes?
