Switch
Ideal voltage controlled switch
Library
Analog/Basic
Description
The Ideal Voltage Switch is a voltage switch that is controlled by an input on/off signal control.
The switch is on or off based on the threshold of the input voltage. The controlling current flows through the specified voltage source.
The direction of positive controlling current flow is from the positive node (+), through the source, to the negative node (-).
Hysteresis effect can also be taken into account when setting the hysteresis voltage.
