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)

  Switch resistance when the Switch is closed

  Properties : Type 'vec' of size 1.

• Resistance in Off state (Ohm)

  Switch resistance when the switch is open

  Properties : Type 'vec' of size 1.

Default properties
