About MFJ-1704N* - 4-Way Coax Switch

The 1704N has a replaceable lightning/surge protection pellet, and centre ground position. When in the centre position, all connectors are disconnected and grounded. If the switch is turned to an active connector, all of the others are automatically grounded.The active connector is automatically protected with the replaceable lightning/surge protector.

Grounding requirements :

A separate external ground wire must be used with this switch. The wire should be connected to either of the through holes of the base plate. The lightning protector pellet will not work without a good ground. Paint should be removed from the base plate at the point of connection to provide a good solder surface.
