<p>When selecting components for mining, construction, or heavy industry applications, reliability and robustness are key. The non-illuminated mushroom pushbutton offers these qualities with a focus on durability and performance. Designed for environments that demand resilience, this product meets several rigorous standards and approvals such as EN IEC 60947-5-1, EN IEC 60947-5-5, EN IEC 60073, EN IEC 60529, UL 508, and CSA C22.2 No. 14.</p><p>This pushbutton is built to withstand harsh conditions with an impressive degree of protection rated at IP66. This ensures excellent resistance against dust ingress and powerful water jets from any direction—ideal for the challenging settings found in industrial operations. It operates efficiently within a wide ambient temperature range from -30 to 70 degrees Celsius.</p><p>The button features a screw connection type which provides secure electrical connections necessary for high-demand environments. With a rated insulation voltage of up to 690 V and a rated impulse withstand voltage of 4 kV, it stands prepared to handle significant electrical stress without compromising safety or functionality.</p><p>The actuator type is designed as a mushroom with a diameter of 40 mm—a size that balances accessibility with precision control in emergency situations or regular operational use. Its momentary function allows the switch to revert back once pressed ensuring quick response times in critical scenarios.</p><p>Constructed with metal bezel material ensures additional durability against mechanical impacts while maintaining its structural integrity over time—a crucial factor when used extensively in demanding sectors like mining or construction.</p><p>A yellow button colour enhances visibility against various backgrounds making it easy to locate quickly during operation—a practical feature where swift action is often required.</p><p>With its cutout size matching the actuator diameter at 40 mm installation becomes straightforward fitting seamlessly into existing setups while minimizing downtime during integration processes.</p><p>The contact configuration includes one normally open (1NO) contact providing reliable circuit completion when activated supporting up to a rated thermal current of ten amperes (10 A).</p><p>Overall this robust industrial-grade component combines essential technical specifications tailored specifically towards heavy-duty applications ensuring it meets both safety standards and operational efficiency requirements effectively meeting your project&#39;s needs without compromise.</p>
