Distinctive
Characteristics
Each half of the rocker face is distinctly illuminated due to partitioned
rocker construction and dual lamps.
B
Snap-in mounting allows fast, easy installation
of switch into panel.
Stainless steel retaining clips provide secure
mounting over a wide range of panel
thicknesses.
Dual incandescent or neon lamps operate
independently of each other.
Front panel relamping.
Stationary lamp sockets are independent of rocker actuation,
protecting lamps from damage due to shock and vibration.
Switch contacts are rated at 10 amps 125V AC which makes these
devices well-suited for various power switching applications.

LAMP CODES & SPECIFICATIONS
Electrical specifications are determined at a basic temperature of 25°C. Lamp circuit is independent of switch operation.
For dimension drawing of lamps see Accessories & Hardware section.
For neon, if the source voltage is greater than rated voltage, a ballast resistor is required. The ballast resistor calculation and more
lamp detail are shown in the Supplement section. Neon not for use with green lamp cover or blue and green filters.
