In 12v mode, the parallel setting connects both batteries to power all outputs equally, while the series setting dedicates one battery to camera power and the other to auxiliary and focus outputs.
The switch setting may matter when powering high-draw equipment like a RED camera that requires separate power lines.
The switch can enable isolated 12v power output from the auxiliary port for accessories.
Newer steadicam models replaced this switch functionality with dedicated power blocks.
The switch was originally designed to support equipment like high-speed cameras that require two separate power sources.

The original poster was uncertain about which mode their rig was operating in due to a broken switch.
The switch has no function in 24v mode.
One respondent acknowledged uncertainty about whether the switch actually affects normal operation.
The practical benefit for typical steadicam operation remains unclear.
