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.
