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.
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).*
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

• 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
• LED output to remotely indicate switch state
• Tin-plated copper studs for maximum conductivity and corrosion resistance
• Label recesses for circuit identication
• PNs 7712 and 7714 include a Remote Control Switch PN 2155

Overview of Application
To connect battery bank to load,
or combine battery banks
With Override Knob in (REMOTE position),
push button until latched (Push to Latch On).
To disconnect battery bank from
load, or isolate battery banks that
are connected
Rotate Override Knob to right to release button
from Latch On mode (button pops up). Rotate
Override Knob to left (REMOTE position).
To prevent remote operation
Rotate Override Knob to right
(LOCK OFF position).
To secure for servicing
With Override Knob in (LOCK OFF position),
pass cable tie through hole.

Remote LED Indicator embedded in PN 2155 SPDT ON-ON Contura Switch
indicates Remote Battery Switch state or condition as follows:
LED INDICATION REMOTE BATTERY SWITCH STATE OR CONDITION
LED is OFF Remote Battery Switch is OFF
LED is ON Remote Battery Switch is ON
LED double blinking ON-OFF
Manual override--check Remote Battery Switch for switch states.
OR Remote Battery Switch mechanical failure
‡
Predicted performance
* Although a SPST switch may be used if desired, use of a SPDT switch improves immunity to inadvertent
switching if the controls become damp.
Emergency Manual Control Override Operations
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.
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.
