<p>When selecting components for industrial and commercial applications, reliability and adherence to standards are crucial. The product in focus here is an illuminated mushroom actuator switch designed for robust environments such as mining, construction, and heavy industry. It boasts a rated voltage of 12 VAC/DC, making it versatile for various electrical systems.</p><p>This switch is built with a degree of protection rated at IP66, ensuring it&#39;s dust-tight and protected against powerful water jets—a vital feature for harsh conditions often encountered in its intended applications. Compliance with standards like EN IEC 60947-5-1, EN IEC 60947-5-5, EN IEC 60073, EN IEC 60529, UL 508, and CSA C22.2 No. 14 further guarantees its performance and safety across different regulatory landscapes.</p><p>Designed to withstand ambient temperatures ranging from -30 to 70 degrees Celsius, this product maintains functionality under extreme weather conditions—be it the freezing cold or sweltering heat typical of outdoor industrial sites. The faston connection type simplifies installation while ensuring secure connections.</p><p>With a rated insulation voltage of 690 V and a rated impulse withstand voltage of 4 kV, the switch is well-equipped to handle high voltages safely. Its contact configuration is set at 2NC (two normally closed contacts), which can be critical in fail-safe designs where circuit interruption is necessary if the system loses power.</p><p>The actuator itself features a substantial mushroom design with a diameter of 40 mm—ideal for emergency stop functions due to its size and visibility. The green illumination provided by the BA9S lamp type enhances its visibility even further in dimly lit environments.</p><p>Functionality-wise, this switch operates on a maintained basis; once activated it remains engaged until manually reset—an essential characteristic for emergency stop applications where immediate cessation of operations is required until issues are resolved.</p><p>Constructed with a metal bezel material that adds durability while maintaining aesthetic appeal within control panels or machinery interfaces—the cutout size also matches the actuator diameter at 40 mm ensuring seamless integration into existing setups without additional modifications.</p><p>Included accessories such as an operator contact block maintained accessories power supply (lamp block) along with the lamp itself ensure that you have everything needed right out of the box enhancing ease-of-use during installation procedures typically expected in demanding work environments found within mining construction heavy industries among others suitable settings.</p>
