The APEM Panel Switches IRR3S422L0S is a high-reliability microswitch-based autoswitch engineered for industrial environments. This panel switch combines IP67-rated sealing, tactile feedback, and a flat round actuator for optional marking to ensure precise operation in challenging conditions. With a mechanical life of 1,000,000 cycles and a current rating of up to 5 A for resistive loads, it provides dependable performance across a wide temperature range from -20°C to +85°C. The switch's robust construction, including 1 GΩ insulation resistance at 500 VDC and 750 Vrms dielectric strength, ensures long-term reliability in critical applications.
The IRR3S422L0S delivers reliable electrical performance with a maximum current rating of 5 A for resistive loads at 250 VAC. It features a 100 mΩ max. initial contact resistance and 750 Vrms dielectric strength between terminals, ensuring stable operation under varying electrical conditions. The switch supports both NO (Normally Open) electrical functions and operates within a wide temperature range of -20°C to +85°C.
Engineered for harsh industrial environments, the IRR3S422L0S meets IP67 standards for dust and water resistance, as well as IEC 512-6 salt spray testing (test 11f). This robust sealing ensures long-term functionality in outdoor or corrosive settings without compromising performance.
With a total travel of 1.6 mm (±0.3 mm typical) and an operating force of 4 N (±2 N), the switch provides precise actuation while maintaining high mechanical durability. The 1,000,000-cycle mechanical life ensures extended service life even in high-frequency applications.
The switch features solder lug terminals for secure electrical connections and a flat round actuator suitable for optional marking. It is available in both illuminated and non-illuminated versions, with a maximum operating torque of 0.8 Nm applied to the nut. The panel thickness is 3 mm (max), making it compatible with standard industrial panel assemblies.
