Switch dialog box

Use the Switch dialog box to view and edit the properties of the selected switch.

To open the Switch dialog box, double-click the switch icon on the Interface layer, or select the switch and then choose Open Selection from the Interface menu (or right-click switch icon and then choose Open from the menu that appears).

Show switch as

Select whether you want the switch to appear as a Toggle switch or a Push Button switch .

Note: If you want to have a switch that links two or more on/off entities so that only one is turned on at any given time, select the Push Button option and then select the Chaining check box. The Chaining option is not available for toggle switch.

Type of switch

Select the type of switch that you want:

• Converters – Select this option to assign the switch to a converter. When the switch is turned on, the associated converter has a value of 1. When the switch is turned off, the converter has a value of 0.
• Sectors – Select this option to assign the switch to a sector. When the switch is turned on, the Run sector(s) command is available, the associated sector is selected (in the Sector Specs dialog box), and choosing the command runs the sector associated with the switch. When the switch is turned off, the associated sector does not run when the command is used.
• Sensi on/off – Select this option to use the switch to turn on and off sensitivity analysis for the next run. When the switch is turned on the sensitivity settings currently specified in the Sensitivity Specs dialog box are used for the next run. When the switch is turned off, the model runs in normal, single-run mode.
• Modules – Select this option to assign the switch to a module. When the switch is turned on, the Run module(s) command is available, the associated module is selected (in the Sector Specs dialog box), and choosing the command runs the module associated with the switch. When the switch is turned off, the associated module does not run when the command is used.

Chaining

Select this check box to have a switch that links two or more on/off entities so that only one is turned on at any given time.

To use the chaining feature, select two to ten entities from the "Allowable" list and add them to the "Selected" list.

Note: This check box is available only if you select the Push Button switch option.

Allowable

Displays the list of entities (converters, sectors, or modules) that can be associated with the switch. The contents of this list changes depending on your selection in the Type of switch box. Entities that are already associated with other switches in the model appear in gray and cannot be selected.

Use this list to select the entity that you want to associate with the switch you are defining.

Notes: If the switch is associated with Converters and you selected the Chaining check box, you can select up to ten converters from the "Allowable" list.

When you assign a switch to a converter, the converter is unavailable to connect to other input devices.

You can assign switches only to converters that are defined as constants.

You cannot assign a switch to a stock, a flow, or to a converter that contains equation logic.
