I don't think US currently has any guarded switches in stock. I recently purchased a ready-to-ship saber and requested a guarded switch, and got a latching AV switch instead. this has been a common "upgrade" for months now. You might check with The Custom Saber Shop (the one "other guy" that I think we're allowed to mention here).
So... as mentioned in my OP.... they ONLY have Guarded switches in their parts section. No AV.
And, also mentioned, I've had issues with how long the TCSS switches are in the past.
I guess the important thing from this, is I was unaware we were restricted to mentioning other companies to get parts from.
