Current controlled ideal switch

Description

The switching behaviour of the ideal opening switch is controlled by the input signal control: off or on.

The switch has three distinct modes of current control,depending on the value of the threshold current value.

The direction of positive controlling current flow from the positive node (+), through the source, to the negative node (-).

Hysteresis effect can also be taken into account setting the hysteresis current.
