<p>The MMS2 series key-operated switch is a robust and reliable choice for industrial and commercial applications, designed to meet stringent standards while offering straightforward functionality. Built with durable metal construction, this non-illuminated switch can withstand challenging environments, operating efficiently within temperatures ranging from -30 to 70 degrees Celsius.</p><p>One of the standout features of this product is its high degree of protection rated at IP66. This ensures that the switch is dust-tight and protected against powerful water jets, making it suitable for both indoor and outdoor use in harsh conditions. The faston connection type allows for quick and secure installation, minimizing downtime during setup or maintenance.</p><p>Engineered with safety in mind, the MMS2 series complies 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 as well as UL 508. These certifications underline its reliability and compatibility with global electrical systems.</p><p>With a rated insulation voltage of up to 690 V and an impulse withstand voltage of 4 kV, this switch is built to handle high-voltage applications effectively. It features a contact configuration of two normally open (2NO) contacts which provide versatility in circuit design by allowing current flow only when activated.</p><p>The actuator type is a key mechanism which offers added security by requiring a specific key for operation—ideal for situations where controlled access is necessary. The maintained function means that once activated into position B or C using the key actuator, it will remain in that state until manually changed back—offering stable operation without constant manual intervention.</p><p>Rated for a thermal current of up to 10 A, this switch provides ample capacity for various electrical loads while maintaining efficient performance across different settings. The cutout size requirement stands at 22 mm ensuring compatibility with standard panel designs.</p><p>Additionally equipped with LED block light types even though not illuminated itself—this feature can be beneficial if integrated into broader systems requiring visual status indicators elsewhere on panels or dashboards connected through similar blocks within setups utilizing such complementary components effectively across installations where needed seamlessly integrating into existing frameworks easily adaptable thus enhancing overall utility value significantly without compromising integrity over time due diligence considered throughout lifecycle usage scenarios anticipated accordingly maximizing return investment decisions made wisely based informed understanding technicalities involved inherently associated therein ultimately delivering satisfaction end-users alike consistently proven track record established reputation trusted source solutions sought after industry professionals globally recognized respected acknowledged achievements attained continually strive excellence pursuit innovation advancement field expertise exemplified dedication commitment quality service provided unparalleled experience unmatched marketplace today tomorrow beyond MPN: MMS2</p>
