<p>When selecting an industrial control device, understanding the specifications is crucial to ensure it meets your technical requirements. The MMS Series non-illuminated switch offers a robust solution for various applications, combining durability with precise functionality.</p><p>Constructed from high-quality metal and finished in black, this switch is designed to withstand harsh environments. It operates efficiently within a temperature range of -30 to 70 degrees Celsius, making it suitable for diverse Australian climates and demanding industrial settings.</p><p>The switch&#39;s IP66 degree of protection ensures complete resistance against dust ingress and powerful water jets, providing reliability in both indoor and outdoor installations. This level of protection makes it ideal for industries where exposure to moisture or particulate matter is common.</p><p>Complying with several international standards such as CSA C22.2 No. 14, IEC/EN 60073, IEC/EN 60529, IEC/EN 60947-5-1, IEC/EN 60947-5-5, and UL 508 highlights its adherence to safety and performance benchmarks recognized globally. These certifications assure users of its quality and compatibility with existing systems.</p><p>The MMS Series features a screw connection type that facilitates secure installation while maintaining ease of maintenance or replacement when necessary. Its rated insulation voltage stands at an impressive 690 V, catering to high-voltage applications without compromising on safety.</p><p>With a contact configuration of 4NO (four normally open contacts), this switch provides flexible circuit integration options. The rated impulse withstand voltage is set at 4 kV which underscores its resilience against transient overvoltages often encountered in industrial environments.</p><p>The actuator type is a short handle designed for maintained operation—meaning the switch remains in its selected position until manually changed by the user. This feature supports stable control processes where continuous operation in one state is required without constant manual intervention.</p><p>Additionally, the rated thermal current capacity of up to 10 A allows it to handle substantial electrical loads effectively while minimizing risks associated with overheating or circuit failures during prolonged use.</p><p>Designed with practicality in mind, the cutout size measures at an industry-standard diameter of 22 mm facilitating seamless integration into existing panels or enclosures without requiring extensive modifications.</p><p>Finally, the maintained positions labeled A through D offer multiple preset configurations ensuring versatility across different operational scenarios whether it&#39;s starting/stopping machinery or controlling auxiliary functions within complex systems—all backed by reliable engineering precision inherent in every unit produced under this series banner: MMS</p>
