MOS Low-Side Switch Board (BS-ELE-MOSLS series)
A compact, high-current MOSFET power control module that switches the negative (low) side of a load and accepts logic-level input from a latching switch, enabling centralized power architectures with distributed manual control points. It is used to safely control lights, thrusters, or solenoids at currents beyond what a subsea rotary switch can handle directly.
