Ideal for high-reliability systems requiring tactile feedback and optional illumination.
The APEM Panel Switches IRR3V252 is a high-reliability, microswitch technology autoswitch engineered for demanding industrial environments. Featuring an IP67-rated sealed construction, this switch delivers exceptional durability with a 1,000,000-cycle mechanical life and 1 GΩ insulation resistance at 500 VDC. Its 1.6 mm total travel and 4 N operating force ensure precise actuation, while the screw terminal design supports up to 4 A continuous current. The switch includes tactile feedback, optional illumination, and a flat round actuator for marking, making it suitable for applications requiring robust, long-term operation in extreme conditions.
The IRR3V252 delivers reliable electrical performance with a maximum current rating of 5 A at 250 VAC for resistive loads. 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 operates within a temperature range of -20°C to +85°C, accommodating extreme environmental conditions.
Engineered for harsh industrial settings, the IRR3V252 meets IP67 standards for dust and water resistance, with salt spray testing compliance (IEC 512-6, test 11f). Its robust construction withstands temperatures from -20°C to +85°C and operates reliably in salt spray environments, making it ideal for outdoor or marine applications.
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 with minimal wear. The mechanical life of 1,000,000 cycles ensures long-term reliability, while the screw terminal design supports up to 4 A continuous current for high-load applications.
The flat round actuator allows for optional marking and tactile feedback, enhancing user experience. The switch is available in both illuminated and non-illuminated variants, with a 3 mm panel thickness (max) for seamless integration into industrial panels. Soldering is compatible up to 320°C for 3 seconds, facilitating reliable assembly.
