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).*
* Although a SPST switch may be used if desired, use of a SPDT switch improves immunity to inadvertent
switching if the controls become damp.

• Magnetic Latch (ML) - draws very low current continuous and draws
moderate current for very short time when changing state
• Silver alloy contacts provide high reliability for switching live loads
• Manual override provides LOCK OFF capability for servicing and ON/OFF control with or without power
• LED output to remotely indicate switch state
• 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 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
To connect battery bank to load, or combine
battery banks
Set remote switch 2155 to position marked “ON”.
Remote LED indicates closed connection.
To disconnect battery bank from load, or
isolate battery banks that are connected
Set remote switch 2155 to position marked “OFF”.
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.

CAUTION
If the ML-RBS Relay state is changed using the Manual Control Knob to a state that is
different than the Remote Switch 2155, the relay state will automatically change to match the Remote Switch
state after 10 minutes. The two scenarios where this will occur are shaded in the table above.
