Overview of Application
Marine Electrical Products
The ML-Series Remote Battery Switch provides high-current carrying and switching under load.
The Remote Battery Switch should be installed close to the battery banks to avoid voltage drop.
ML–Series
Remote Battery Switch (RBS)
Install a single pole double throw (SPDT) or single pole single throw (SPST) control switch in a convenient
location near other electrical controls or companionway to allow quick access in the event of an emergency
(see Illustration on reverse).*
PN 7712 / PN 7712B / PN 7714 / PN 7714B
• Magnetic Latch (ML)—draws very low current (<13 mA in the ON state and <8 mA in the OFF state) and draws
moderate current for very short time when changing state
• Silver alloy contacts provide high reliability for switching live loads
• Manual control override knob provides an added level of safety allowing control with or without power,
and offering LOCKED OFF capability for servicing
The Manual Control Override Knob provides:
• an added level of safety that allows manual ON-OFF control with or without power
• LOCK OFF for servicing the electrical system
• LED output to remotely indicate switch state
The remote LED embedded in PN 2155 indicates a closed connection between battery bank and load, or
between two battery banks when used as an emergency cross-connect.
• Tin-plated copper studs for maximum conductivity and corrosion resistance
• Label recesses for circuit identification
• PNs 7712 and 7714 include a Remote Control Switch PN 2155
Remote Operation. PN 2155 (SPDT, ON-ON) Remote Control Contura Switch in the ON position can either
connect the battery bank to the load or combine two battery banks. In the OFF position it can either
disconnect a battery bank from a load or isolate two batteries from each other.
