I was expecting that VoltageSwitch behave like when used with a negative hysteresis:

If Vh is negative, like in this case, the switch will smoothly transition between the on and off impedances.

But smooth transition between the on and off impedances when used with negative hysteresis seems to be not implemented.

I want to ask kindly to add this feature.
