Is there a switch that turns on for a specific amount of time? That does not depend on the system's time.

Is there a switch in simulink that turns on for a specific amount of time then turns off?
For context, the orange signal runs for 1s and I want a switch that becomes closed when the orange signal < 0 and sends a yellow signal that runs for 0.5s.
Currently i am using a switch that is set at >= -0.00001 (when the signal goes down)
Any help is appreciated! Thank you!

I need something like this. This is done manually with a pulse generator, but I need it to be conditioned by the orange signal.

An Enabled Subsystem can be used for your requirement. Whenever orange signal is less than 0, an enabler can be set to 1 and send to Enabled Subsystem which runs yellow signal for 0.5 seconds. A Switch can be used whose output can be passed to Scope.

How do I run the yellow signal for o.5 seconds or 5 seconds? I see no time setting in the enabled subsystem.
