<p>The MMS series key-operated switch is a robust and reliable choice for industrial and commercial applications, designed to meet the demands of various operational environments. Its non-illuminated design ensures simplicity while maintaining essential functionality.</p><p>Constructed from durable metal, this switch is built to withstand challenging conditions with an operational temperature range from -30 to 70 degrees Celsius. This makes it suitable for both cold storage facilities and high-temperature industrial settings. The IP66 degree of protection ensures that the switch is dust-tight and protected against powerful water jets, making it ideal for harsh environments where reliability is crucial.</p><p>The MMS series complies with several key standards and approvals, 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. These certifications reflect its adherence to international safety and performance standards.</p><p>Featuring Faston connection type for quick installation or replacement in complex systems without compromising on security or durability. The rated insulation voltage of 690 V provides a strong barrier against electrical faults while the rated impulse withstand voltage of 4 kV ensures resilience against transient overvoltages in industrial power networks.</p><p>With a contact configuration of 2NO (two normally open contacts), this switch offers straightforward integration into control circuits requiring momentary action—a common requirement in automation systems where precise control inputs are necessary. The actuator type being key-operated adds an extra layer of security by preventing unauthorized operation.</p><p>Rated thermal current stands at a substantial 10 A which supports higher load applications without overheating risks ensuring consistent performance even under demanding conditions. The cutout size of 22 mm allows easy mounting into standard panels or consoles simplifying installation processes across different setups.</p><p>Maintained positions A, C, B provide flexibility in setting the desired operational mode according to specific needs enhancing adaptability across diverse system requirements within your facility&#39;s infrastructure ensuring that you have full control over your operations at all times without compromise on safety or efficiency.</p>
