Sequel 2 electronics switch function?

[Nikolai]

Hi there, Does anyone know the function of this switch on my Sequel 2 electronics board? It has a black housing with red switch that can be set to "o" or 'l"

Thanks!

Looks like it's at the output of the HV power supply, so guessing it might allow for two different voltages, so the same board could be used on multiple models with different size panels.
Unfortunately, we do not have a schematic for the Sequels. However, this thread might prove useful to you: Help with Sequels

Thanks!
