Ideal Transfer Switch
SIMPLORER 6.0 — Manual 105
>>Basics>Circuit>Ideal Switches
The component represents an ideal electrical transfer switch. If the control signal is greater
than '0', the nodes N1 and N2 are connected and the nodes N1 and N3 are disconnected. Because
it is an ideal switch, the resistance of the line connection is zero and the resistance of
the disconnection is infinite. If the control signal is lower than or equal to '0', the line between
I and N3 is connected.
Since the switch behaves as an ideal, physically meaningful circuits must be obtained in both
ON and OFF switching states.
The ideal switch is represented as an Animated Symbol; that means the switch symbol will
change during the simulation depending on the corresponding control signal. To display the
states with the switch, check the «Animated Symbols» box in the «System» tab in
SHEET>PROPERTIES.
v1() t = 0 and i2() t = 0, if the control signal > 0 (On)
i1() t = 0 and v2() t = 0, if the control signal ≤ 0 (Off)

«Control Signal»
Defines the switch control signal. Control parameter type. Enter a numerical value, a variable,
or an expression in the text box or use the pin to connect a quantity.
� � «Use pin»
If the box is checked, the control signal is defined by the quantity connected to the pin, otherwise
the name in the text box is used.
