Distinctive Characteristics
Full face, Neon illumination in choice of red, amber, or green.
Neon lamp suited to 125V AC applications.
9-amp electrical capacity in compact body.
Built-in resistor for direct connection to
125V AC power source.
Low cost molded rocker.
Front panel, snap-in mounting assures
labor-saving installation.
Single-break, snap-acting contact mechanism
gives smooth actuation and audible feedback.
Quick-make, quick-break characteristic limits arcing
and prolongs electrical life.
Stable stationary contact construction for high reliability.
Offset terminal alignment gives outstanding insulation resistance and
dielectric strength.
Quick connect terminals (.187”/4.75mm) can be used with connectors. Actual Size
