<p>The MMS series momentary switch is a robust and reliable choice for industrial and commercial applications, designed to meet the rigorous demands of modern electrical systems. This green, illuminated switch operates efficiently under both 24 VAC and VDC, offering flexibility in various power environments. Its metal construction ensures durability, making it suitable for harsh conditions ranging from -30 to 70 degrees Celsius.</p><p>Engineered with an IP66 degree of protection, this switch is resistant to dust ingress and powerful water jets, making it ideal for outdoor or challenging indoor environments where exposure to elements is a concern. The adherence to 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 further underscores its reliability and safety credentials.</p><p>The MMS series features a long handle actuator type with a momentary function that returns to its original position after activation. This design is particularly beneficial in operations requiring frequent manual intervention without maintaining the circuit&#39;s closed state. The contact configuration of three normally closed (3NC) contacts enhances safety by ensuring circuits are interrupted when not actively engaged.</p><p>With a rated insulation voltage of 690 V and an impulse withstand voltage of up to 4 kV, this switch can manage high-voltage scenarios while minimizing risk from transient overvoltages. It supports a rated thermal current of up to 10 A, catering well to medium-duty applications that demand consistent performance without overheating.</p><p>Installation is straightforward due to its screw connection type which provides secure attachment within control panels or machinery housings. The cutout size requirement stands at a standard 22 mm diameter—a common dimension that allows easy integration into existing setups without the need for additional modifications.</p><p>For enhanced visibility in low-light conditions or complex panel arrangements, the LED block light type offers clear illumination in green—indicating operational status at a glance which aids quick identification during maintenance or troubleshooting processes.</p><p>Overall maintained positions labeled as A,C,B provide users with versatile operation modes tailored for specific task requirements ensuring adaptability across different industrial settings.</p>
