Ideal electrical closer
Electrical/Analog/Ideal
The ideal closing switch has a positive pin p (left) and a negative pin n (right). The switching behaviour is controlled by the input signal control (top). If control > 0, pin p is connected with negative pin n. Otherwise, pin p is not connected with negative pin n.
In order to prevent singularities during switching, the opened switch has a (very low) conductance Goff and the closed switch has a (very low) resistance Ron. The limiting case is also allowed, i.e., the resistance Ron of the closed switch could be exactly zero and the conductance Goff of the open switch could be also exactly zero. Note, there are circuits, where a description with zero Ron or zero Goff is not possible.
