The switch is now configured as a normally open contact in order to meet Marine Classification Society requirements. A Hirschmann type connector has been added to the group. The new connector will provide a better seal at the junction box and is more user friendly. The revised groups also feature a new cover and plate assembly for the oil level switch.

The new 1V-2727 Level Switch Assembly is used in the revised contactor groups. The new 169-9519 Cover and 169-9517 Plate Assembly are also used in the revised contactor groups. See the
