Distinctive Characteristics
B
Pushbuttons
Each half of the rocker face is distinctly illuminated due to partitioned
rocker construction and dual lamps.
Rockers
Toggles
Series LW
Power-Rated Snap-in Rockers
Programmable Illuminated PB
Numerous lighting effects achievable by using white
or clear rocker with colored filters or lamp covers,
plus using different colors on each side of rocker.
Snap-in mounting allows fast, easy installation
of switch into panel.
Rotaries
Keylocks
Stainless steel retaining clips provide secure
mounting over a wide range of panel
thicknesses.
Slides
Dual incandescent or neon lamps operate
independently of each other.
Tactiles
Front panel relamping.
Tilt
Stationary lamp sockets are independent of rocker actuation,
protecting lamps from damage due to shock and vibration.
Touch
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.
