Description
The commuting switch has a positive pin p and two negative pins n1 and n2.The switching behaviour is controlledby the input signal control. If control is true, the pin p is connectedwith the negative pin n2. Otherwise, the pin p is connected to the negative pin n1.
In order to prevent singularities during switching, the openedswitch has a (very low) conductance Goffand the closed switch has a (very low) resistance Ron.The limiting case is also allowed, i.e., the resistance Ron of theclosed switch could be exactly zero and the conductance Goff of theopen switch could be also exactly zero. Note, there are circuits,where a description with zero Ron or zero Goff is not possible.
Please note:In case of useHeatPort=true the temperature dependence of the electricalbehavior is not modelled. The parameters are not temperature dependent.
