Meets IP65 of IEC60529 standards (similar to NEMA 4 and 13), providing dust tight and splashproof panel seal protection. Tamper resistant 18mm square actuator. Short body of .965” (24.5mm) conserves behind-panel space. Distinctive long stroke and light touch actuation for clear indication of circuit status. Choice of cap colors includes clear, red, green, amber, or metallic silver for enhanced panel appearance. Brilliant illumination with multiple LED colors. Bezel color options in silver 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. Actual Size Custom legends on actuator available.
