Switch and Diode: definition (structure)
Definition
A switch and diode components are defined by:
- a name (and a comment)
- a model
- specific characteristics depending on the model
- a command
- two terminals
Name
The name permitting the identification of the component is given by the user when this is created by him.
A comment (optional) can be added to the name.
The name and the comment are displayed by default in the graphic zone close to the symbol.
Switch and Diode: description
Characteristic quantities, necessary for the description of the switch and diode components are presented in the table below.
