• Most EN catalog listings are MIL-PRF-8805 compliant for stringent
 military and non-military applications
contacts for reliably controlling electrical loads from
 less than 0.5 A [low energy/logic level] up to 15 A (power duty)
or providing redundant circuit capabilities
• Rugged stainless steel housing and bushing
• All-metal drive train for consistent operating 
• Miniature package size [400EN Series and 600EN Series]
reduces housing diameter by 30 % for smaller space required on equipment
• MIL-PRF-8805 symbol 4 (resilient) sealing to keep dust,
 water, and ice from entering the switch enclosure
• Gold-bifurcated, gold-plated, or silver-alloy switch
