The APEM Panel Switches IRR3F4B2 is a high-reliability microswitch-based autoswitch engineered for industrial control systems. This panel switch combines IP67-rated sealing, tactile feedback, and a flat round actuator for optional marking to ensure precise operation in harsh environments. With a mechanical life of 1,000,000 cycles and a current rating of up to 5 A at 250 VAC, it meets stringent industrial demands while maintaining consistent performance across a wide temperature range from -20°C to +85°C. The switch's robust construction and microswitch technology provide reliable switching with minimal contact resistance and high insulation resistance, making it suitable for critical applications where durability and precision are essential.
The IRR3F4B2 delivers precise electrical switching with a maximum current rating of 5 A at 250 VAC. It supports 50,000 cycles for function 7 and 25,000 cycles for function 8, ensuring reliable operation under varying load conditions. The switch maintains an initial contact resistance of 100 mΩ max and a dielectric strength of 750 Vrms between terminals, with 2,000 Vrms between terminals and frame for enhanced safety.
Engineered for extreme conditions, the IRR3F4B2 operates within a temperature range of -20°C to +85°C (-40°F to 185°F). Its IP67 rating provides full dust and water protection, with salt spray resistance meeting IEC 512-6 test 11f. This ensures long-term performance in harsh industrial environments without degradation.
The switch features a total travel of 1.6 mm (±0.3 mm typical) with an operating force of 4 N (±2 N). It is designed for 1,000,000 mechanical cycles, making it ideal for applications requiring high switch longevity. The flat round actuator allows for optional marking, enhancing usability in complex control panels.
With flying leads for terminal connections, the IRR3F4B2 is compatible with standard panel mounting. The switch supports both illuminated and non-illuminated versions, providing flexibility in visual feedback. Its 3 mm panel thickness (max) ensures compatibility with most industrial enclosures while maintaining structural integrity.
