500A ML-Series Remote Control Solenoid Switch - 12V DC

This is a great device!
No more crawling into the engine compartment, lifting floorboards, or piling up cushions to operate your On/Off battery switch. You can use this solenoid battery switch to connect or disconnect your battery banks remotely from the helm, nav station, or control panel, without having to go below to access the actual battery switch.
What a convenience!

Unlike typical solenoids which are only activated when a current is present (like your car starter motor solenoid), the magnetic latching feature of these solenoid battery switches means that the battery switch will remain in either state (contacts open or closed) until changed by the operator.
This is possible due to continuous passive assistance from the magnet to keep it in either the On or Off state.

If the safety feature of a manual backup control is desired in your installation, you can use the ML Remote Solenoid Battery Switch with Manual Control version of this switch (#7700/7702), which has a manual on/off knob right on the solenoid to allow switching even if there is a loss of power - see Related Products, below.

For use with battery banks for inboard gasoline or diesel engines, windlasses, thrusters, or inverters, this switch reduces long runs of heavy battery cables because it activates with low currents through small wires. No current draw, except to actually change the on/off configuration of the switch.
