Hi everbody, I used a switch in simulink to switch among 3 signals. But after got 3th signal it did not return to 1st signal to repeat this process. So if I want the switch do that, how must I do? Thanks lot.

I assume you are referring to the Multiport Switch. You need to drive the control input with a signal that varies between 1 and 3. If it is 1, it will pass through the first input, if it is 2, the second input, etc... Depending on what it is you're trying to do, you can probably use a Repeating Sequence or a Repeating Sequence Stair block for that purpose.
HTH,
Arnaud
