<p>The MMS2 Series key-operated switch is a robust and reliable choice for industrial and commercial applications. Engineered to meet stringent requirements, this non-illuminated switch offers excellent performance in challenging environments. Its metal construction ensures durability and longevity, making it ideal for heavy-duty use.</p><p>Designed to operate within a wide temperature range of -30 to 70 degrees Celsius, the MMS2 Series switch can withstand harsh conditions without compromising functionality. The IP66 degree of protection further enhances its resilience against dust and water ingress, ensuring reliable operation in various settings.</p><p>This product complies with multiple 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. These certifications attest to its quality and safety features, providing peace of mind that the device meets high industry benchmarks.</p><p>For electrical connections, the MMS2 Series utilizes a screw connection type which is known for its secure fitment and ease of installation. With a rated insulation voltage of 690 V and a rated impulse withstand voltage of 4 kV, this switch can handle substantial electrical loads while maintaining operational integrity.</p><p>The contact configuration consists of two normally closed (2NC) contacts which are suitable for applications requiring immediate disconnection upon actuation. The momentary function means the switch returns to its original position after activation unless held manually.</p><p>With an actuator type designed as a key mechanism, it provides additional security by restricting unauthorized access or operation—ideal for controlled environments where operations need careful management.</p><p>Rated at a thermal current capacity of up to 10 A ensures that this switch can manage significant current flows without overheating or failure under normal operating conditions. The cutout size is standardized at 22 mm facilitating easy integration into existing panels or systems with minimal modifications required.</p><p>Additionally equipped with LED light blocks despite being non-illuminated itself allows integration with external illumination systems if needed enhancing visibility during operations when paired appropriately with other components in your setup.</p><p>In summary; whether you&#39;re upgrading an existing system or designing new installations from scratch consider incorporating the MMS2 Series key-operated switches into your project plans thanks largely due not only their technical specifications but also adherence towards globally recognized safety protocols ensuring reliability across diverse application scenarios all backed by solid engineering principles inherent throughout each unit produced within this line-up!</p>
