<p>For professionals in the electrical engineering and automation industries, selecting a reliable switch is crucial for ensuring operational efficiency and safety. The MMS2 series offers a robust solution with its non-illuminated, black metal construction, designed to withstand harsh environments. This product operates efficiently within a temperature range of -30 to 70 degrees Celsius, making it suitable for various industrial applications.</p><p>The switch boasts an impressive IP66 degree of protection, safeguarding it against dust ingress and powerful water jets. This ensures durability in demanding settings where exposure to environmental elements is common. It adheres to rigorous standards including CSA C22.2 No. 14, IEC/EN 60073, IEC/EN 60529, IEC/EN 60947-5-1, IEC/EN 60947-5-5, and UL 508—providing confidence in its compliance with international safety and performance benchmarks.</p><p>A notable feature is its connection type: Faston terminals that simplify installation while maintaining secure connections necessary for industrial operations. The rated insulation voltage stands at an impressive 690 V with a rated impulse withstand voltage of 4 kV—parameters that highlight the switch&#39;s capability to handle high voltages safely.</p><p>The contact configuration is set at 1NC (normally closed), which suits applications requiring immediate disconnection upon activation—a key aspect for emergency stop functions or momentary operations where quick response is essential.</p><p>With a short handle actuator type designed for momentary function use, this switch provides tactile feedback without latching into position—a beneficial feature when frequent manual resets are needed during operation cycles.</p><p>Rated thermal current capacity reaches up to 10 A, supporting moderate power loads typical in commercial or light-industrial environments. Its cutout size of 22 mm allows easy integration into standard panel designs without customization hassles.</p><p>Additionally, the maintained positions labeled as C and B offer versatility depending on user requirements or system configurations. While this model includes provisions for LED block types even though it&#39;s non-illuminated by default—offering potential customizability should illumination be desired later on.</p><p>In summary, the MMS2 series combines reliability with flexibility through its durable construction and adherence to stringent standards making it an ideal choice for those needing dependable performance across diverse conditions without compromising on safety or ease-of-use features.</p>
