Distinctive Characteristics
• High quality brushed chrome cap and bezel
options.
• Improved weather durability against ultaviolet
rays.
• Meets IP65 of IEC60529 standards (similar
to NEMA 4 and 13), providing dust tight and
splashproof panel seal protection.
• Short body of .965” (24.5mm) conserves behind-
panel space.
• Tamper resistant 19mm diameter actuator and
18mm square actuator.
• Shortest above-panel dimension (1.8mm) in the
industry for splashproof design making panel flat
and preventing operator error.
• Light weight compared to actual metal switches
due to metal plating on resin.
• Distinctive long stroke and light touch actuation
for smooth actuation and clear indication of circuit
status.
• Choice of cap colors includes clear, red, green,
amber, or brushed chrome for enhanced panel
appearance.
• Metallic silver cap option has bright ring
illumination (round only).
• Bezel color options in brushed chrome or black.
• Available in momentary and alternate action with
latchdown.
• Crisp actuation and clear circuit status provided
by snap-action contact mechanism. Arc barrier
protects against crossover.
• Combination solder lug and .110” quick connect
terminals. Terminals are epoxy sealed to lock out
flux, dust, solvents, and other contaminants, as
well as to secure terminals and improve contact
stability.
