switch controlled by signal

Like the picture showing, the simin block will has a series of data from matlab that only contains 0 and 1. I wanna the switch go to R1 when data is 0 and go to R2 when data is 1 during the simulation. How could I do this ? Thank you.

Please elaborate on below points:

1. You want to change one value of the series or multiple values at same time?
2. What is the purpose of providing series to selection input of switch block, as at a time only one will be connected.

In case if one value to be given to the to selection input of switch block, you can use below options:

1. Use constant block and change its value property using set_param from command window.
2. Use toggle switch of dashboard in model itself and connect it to constant block. You’ll be able to change value through model itself.
