DESCRIPTION
The MS500 Series provides an inexpensive and reliable method of switching 4 to 18 inputs
to a single monitor output using interlocked manual pushbuttons. Included in this series is
the MS540 switcher with two monitor outputs and the capacity to switch up to 40 inputs with
a 14 pushbutton panel.
The MS500 Series Switchers are designed for either looping or terminating operation,
depending on the model.
