Description
The ideal closing switch has a positive pin p and a negative pin n.The switching behaviour is controlled by input signal control.If control is true, pin p is connectedwith negative pin n. Otherwise, pin p is not connectedwith negative pin n.
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.
Use with care:This switch is only intended to be used for structural changes, not for fast switching sequences, due to the quasistationary formulation.
