Simulink Switch Case Block does not update

Hello all together,

I am quite new to Simulink and currently trying to build a model that has two major different states which both can occure during simulation. The two states have different model parameters but feed in exactly the same model.

My thought to do this was to use a switch-case block. By varying the input to 0 or 1 the corresponding model parameters should be used. But here comes the problem: The Action Port only seems to update once. Even when the input of the switch oscillates the output stays the same.

I added the relevant part of the model here:

I would really appreciate your help.

Thanks in advance.

Kind regards, Matthias

I don't quite know enough but why don't you simply calculate both signals at all times using the different parameters and use switch blocks to decide which output signal is fed through?
