I want to use a Single Pole Triple Throw (SP3T) switch in my model. There is no such SP3T block in Simscape but there is a Single Pole Double Throw (SPDT) switch. Is there a way to model a SP3T switch?

Best Answer

There is no Single Pole Triple Throw (SP3T) block in Simscape. However, it is possible to model the same functionality as that of Single Pole Triple Throw (SP3T) using two Single Pole Double Throw (SPDT) switches.
The attached image shows how to go about doing this.
Note: Using two Single Pole Double Throw (SPDT) switches will require two control signals as inputs which will need to be coordinated accordingly.
