Thanks guys...
After a couple hours of reading manuals on their site last night, I stumbled across this as well. This made me feel much more comfortable about using the switch provided.
I've been leaning heavily towards using one of their DPSI units in a 35% Carden I'm building...this cleared up my last concern with the unit.
Does anyone know of any Emcotec dealers besides DesertAircraft in the states? DA only shows a few of Emcotec's products on their site. I haven't called DA to confirm yet, but I assume they can order any Emcotec product even if it's not listed on their site?

Copied from the Emcotec manual:
Because the distribution voltage is switched on electronically (the
switch does not activate any current, but rather only the switch-on
signal), no losses, contact errors or transition resistance occur. This
internal electronic switch is fail-safe. Thus, a switched-on “DPSI RV /
RV Mini“ remains switched on even if, for example, the On/Off switch
is separated or interrupted.
I believe that if this works as advertised then it would qualify as a "fail safe" switching method.
