Disable knob with a switch

[Latenite1]

   Hi All, I am very new to Labview so I am certain there is a very simple way to execute somthing like this. I have a Knob on my VI that will adjust the Noise displayed by a selected signal.  I would like to add two switches to this knob.  One switch to turn all noise on/off reguardless of the current setting of the knob it's self.  I would also like another switch to toggle between gaussian and standard white noise.  Any insight is greatly apperciated!

Similar to above except added property nodes to disable controls when overall switch is unselected.

Don't over-complicate things and clutter the front panel with multiple switches.

I would recommend a simple radio button control with three states (Off|Gaussian|White). Wire it directly to a case structure add it will act like an enum with the control names as items.

Here is a simple example (LabVIEW 8.0):
