Public Sub CloseSwitchRelays (

)

relays: Type: SystemString
A set of relays to close. You can specify a string that contains a comma-delimited list of relays.
waitForSettling: Type: SystemBoolean
If , this method waits for the switches to settle before returning. If , the method returns immediately after the operation. This settling time is controlled through the SettlingTime property.

Exception	Condition
DaqException	The NI-DAQmx driver returned an error.

When you operate relays directly, you circumvent the protection that channel usage types offer. Avoid using this method when you use the ConnectSwitchChannels(String, Boolean) or DisconnectSwitchChannels(String, Boolean) methods because this method does not pass the changes that you make to those methods.
