<p>The MMS2 series key-operated switch is a robust and reliable choice for industrial and commercial applications, designed to meet the rigorous demands of various operational environments. With its non-illuminated design, this switch provides straightforward functionality without unnecessary complexity.</p><p>Constructed from durable metal, it offers excellent resilience in challenging conditions. The operational temperature range of -30 to 70 degrees Celsius ensures that it can perform reliably across diverse climates, making it suitable for both indoor and outdoor installations.</p><p>Its IP66 degree of protection guarantees resistance against dust and powerful water jets, ensuring longevity and reliability even in harsh environments. This makes the MMS2 series ideal for industries where exposure to such elements is common.</p><p>Compliant with several international 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 certifications assure users of its safety and quality assurance across global markets.</p><p>The MMS2 features a screw connection type which simplifies installation while maintaining secure electrical connectivity. Its rated insulation voltage stands at an impressive 690 V with a rated impulse withstand voltage of 4 kV—attributes that ensure safe operation under high-voltage conditions.</p><p>With a contact configuration of one normally open (1NO) and one normally closed (1NC), the switch facilitates versatile control options in circuit designs requiring both opening and closing functions within the same device.</p><p>The actuator type is key-operated with maintained function positions at A and C providing dependable control over machinery or systems that require consistent engagement or disengagement until manually reset by an operator.</p><p>Rated thermal current capacity reaches up to 10 A making it suitable for medium power applications without compromising on performance or safety. Additionally, its cutout size is standardized at 22 mm allowing compatibility with existing panel configurations easing integration into pre-existing setups.</p><p>Though non-illuminated itself this product supports LED block light types offering optional visual indication if necessary through separate components enhancing usability where visibility feedback is desired but not integral within the core unit itself thus preserving simplicity yet allowing flexibility depending on user needs</p><p>In summary whether you&#39;re upgrading existing infrastructure or specifying components for new installations consider integrating this well-engineered solution into your projects knowing you have chosen equipment built upon solid engineering principles backed by reputable standards compliance all wrapped within practical design choices aimed squarely towards professional use cases Manufacturer Part Number: MMS2</p>
