INTRODUCTION: 

The 720-MDO is a high current, remotely activated battery switch. This allows convenient operation with 

the remote switch within easy reach of the user, and the battery switch positioned where cable runs are 

minimized. Reduced cable runs allow smaller section cable to be used, resulting in signifi cant reductions 

in cable cost, plus weight savings.

As well as remote, motorized operation, the 720-MDO can be manually over-ridden. From the “Manual 

Off” position, the switch knob can also be removed, providing security, particularly during servicing.

Designed and constructed for longevity in the marine environment with tinned copper conductors, stainless 

steel nuts and high temperature, fi bre reinforced plastics. The units are ignition protected, provide On/Off 

switching operation, and may be recessed or surface mounted. 

The Version 8 printed circuit boards include the latest developments in digital circuitry, and optical position 

sensing. These result in signifi cant improvements to voltage measurement circuits, switch operation, and 

provide low power consumption.
