Universal field convertible 3-wire switch

摘要

A universal 3-wire switch module is provided for normally open and/or normally closed load control modes. The universal switch module is field convertible from P type DC to N type DC to P type AC to N type AC configurations as programmed by installation wire connection, without internal changes to the switch module. A single switch module replaces the prior dedicated switch modules used for the various configurations. The switch module is further characterized by its versatile application to a wide range of voltage.
