title: LabVIEW: What is the difference between the mechanical actions "Latch until released" and "Switch until released"?
body: <p>In which situations should we use "Latch until released" instead of "Switch until released"? </p>
  
  <p>According to <a href="http://zone.ni.com/reference/en-XX/help/371361H-01/lvhowto/changemechactofboolswitch/" rel="noreferrer">LabVIEW 2011 Help</a>:</p>
  
  <blockquote>
    <p>Latch until released—Changes the control value when you click it and
    retains the value until the VI reads it once or you release the mouse
    button, depending on which one occurs last. You cannot select this
    behavior for a radio buttons control.</p>
    
    <p>Switch until released—Changes the control value when you click it and
    retains the new value until you release the mouse button. At this
    time, the control reverts to its default value, similar to the
    operation of a door buzzer. The frequency with which the VI reads the
    control does not affect this behavior. You cannot select this behavior
    for a radio buttons control.</p>
