you are using https://www.mathworks.com/help/simulink/slref/switch.html which is a switch for Simulink signals. However your inputs are electrical voltages not numeric signals.

You need a switch from the electrical library, https://www.mathworks.com/help/sps/powersys/ref/idealswitch.html

Simulink supports several different "domains" that can only be connected through convertor blocks. Pure signals, electrical signals, fluids: Simulink makes sure that you keep them separate.

Remember though that an ideal electric switch does not correspond to reality. In reality you have to be concerned with overshoot and transients. If you were doing high frequency work those can become substantial problems.
