[Microwave] Switching Setup Question

[Jesse J. Alcorta]

Does anyone have any experience in using multiposition coaxial
switches?  Specifically, I have the chance to purchase a few surplus
switches with the following specs -

SP4T, 12VDC, Failsafe to position 1, break before make, SMA connectors,
rated to 18GHz

I was thinking about using a single 2M IF and one of these switches to
interface a couple of transverters for the higher bands.  Would like
feedback from those that have experimented with such a setup and their
success or failure.  If you blew up a rig I would like to hear from you
and learn from you.  If you your setup works and hasn't "smoked" yet I
want to hear from you as well.
