The APEM Panel Switches IRC3S422 is a high-reliability microswitch autoswitch engineered for industrial control systems. This switch combines IP67-rated sealing, tactile feedback, and a flat round actuator for optional marking to ensure precise operation in harsh conditions. With a mechanical life of 1,000,000 cycles and a 5 A 250 VAC current rating, it meets stringent electrical and environmental demands while maintaining consistent performance across a wide temperature range from -20°C to +85°C. The IRC3S422 is designed for applications where durability, electrical safety, and long-term reliability are critical.
The IRC3S422 operates as a normally open (NO) switch with a maximum current rating of 5 A at 250 VAC for resistive loads. It supports 50,000 cycles for function 7 and 25,000 cycles for function 8. The switch exhibits an initial contact resistance of 100 mΩ max and dielectric strength of 750 Vrms between terminals, with 2,000 Vrms between terminals and frame.
Engineered for extreme conditions, the IRC3S422 withstands temperatures from -20°C to +85°C (-40°F to 185°F). It features IP67 sealing per IEC 60529, ensuring protection against dust and water immersion, with salt spray resistance meeting IEC 512-6 test 11f.
The switch has a total travel of 1.6 mm (±0.3 mm typical) and an operating force of 4 N (±2 N). Its panel thickness is 3 mm max, and it supports a torque of 0.8 Nm max applied to the nut. The screw version handles up to 4 A current, with soldering capabilities at 320°C for 3 seconds.
With an insulation resistance of 1 GΩ min at 500 VDC and dielectric strength of 750 Vrms between terminals, the IRC3S422 ensures robust electrical safety. The switch is designed for 1,000,000 cycles of operation, making it suitable for critical industrial applications where longevity is essential.
