The APEM Panel Switches IRR3S412 is a high-reliability microswitch 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 5 A at 250 VAC, it provides dependable performance for critical applications where environmental resilience and long-term durability are essential.
The IRR3S412 delivers robust electrical performance 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, ensuring long-term reliability in high-demand applications. Initial contact resistance remains below 100 mΩ, and dielectric strength exceeds 750 Vrms between terminals, with 2,000 Vrms between terminals and the frame for enhanced safety.
Engineered for extreme conditions, the IRR3S412 meets IP67 standards for dust and water resistance, with salt spray testing compliance (IEC 512-6, test 11f). It operates effectively across a wide temperature range from -20°C to +85°C (-40°F to 185°F), making it suitable for outdoor installations and harsh industrial settings without degradation.
With a total travel of 1.6 mm (±0.3 mm) and operating force of 4 N (±2 N), the switch ensures precise actuation while maintaining low wear. The 1,000,000-cycle mechanical life guarantees extended service life, even under frequent use, and the screw version supports continuous current up to 4 A for high-load applications.
The switch features solder lugs for secure terminal connections and a flat round actuator for optional marking. Its 3 mm panel thickness (max) ensures compatibility with standard industrial panels, while the 0.8 Nm max torque for nut tightening provides reliable assembly without damage.
