Does anyone know if the bypass switch is a momentary type or not? And if so, if it is a N.O. or N.C. type?

I'm pretty sure it is momentary - check this schematic:

I have that schematic, but it doesn't say anything about the actual type of switches used...

Looking at the schematic, it leads me to believe that it is a standard DPDT switch instead of a momentary type since there appears to be no transistor acting as a switch for the bypass status LED.

Just for the record, I did verify that it is just a standard DPDT switch. The one on my bench has a Carling X-type DPDT switch on it.
