Switch

Switch controlled by external physical signal

Library

Electrical Elements

Description

The Switch block models a switch controlled by an external physical signal. If the external physical signal PS is greater than the value specified in the Threshold parameter, then the switch is closed, otherwise the switch is open.

Dialog Box and Parameters

Parameters Tab

Closed resistance R_closed

The resistance of the switch when it is closed. The parameter value must be greater than zero. The default value is 0.01 Ω.

Open conductance G_open

The conductance of the switch when it is open. The parameter value must be greater than zero. The default value is 1e-8 1/Ω.

Threshold

The threshold value for opening and closing the switch. If the external physical signal PS is greater than this value, then the switch is closed, otherwise the switch is open. The default value is 0.

Variables Tab

Use the Variables tab to set the priority and initial target values for the block variables prior to simulation. For more information, see Set Priority and Initial Target for Block Variables.

Ports

The block has two electrical conserving ports and one physical signal port PS.
