Description

This is a non-ideal two-pole switch. If the explicit input become positive, two pins are connected via a resistor of resistance RON). Otherwise, two pins are connected via ROFF resistance. Note that using this block may result in a stiff model, so try to choose proper error tolerances.

Dialog box

  • Resistance in On state (Ohm)
