Description

When it comes to choosing reliable control components for industrial applications, this non-illuminated mushroom pushbutton switch stands out as a robust option. Designed with practicality and durability in mind, it is well-suited for demanding environments such as mining, construction, and heavy industries. The product features a high degree of protection with an IP66 rating. This ensures that it can withstand dust ingress and powerful water jets from any direction, making it ideal for harsh outdoor or indoor conditions where exposure to the elements is a concern. Safety and compliance are paramount in industrial settings. This pushbutton meets several international standards including EN IEC 60947-5-1, EN IEC 60947-5-5, EN IEC 60073, EN IEC 60529. Additionally, it complies with North American standards UL 508 and CSA C22.2 No. 14, providing reassurance of its quality and safety credentials. Operating efficiently across a broad temperature range from -30°C to 70°C, this pushbutton is versatile enough to handle extreme environmental conditions without compromising performance. The connection type uses Faston connectors which facilitate quick and secure installation—a practical feature for technicians looking to minimize downtime during setup or maintenance procedures. With a rated insulation voltage of 690 V and an impulse withstand voltage of up to 4 kV, this component offers excellent electrical resilience suitable for high-voltage applications. Its contact configuration of two normally open (2NO) contacts provides straightforward momentary operation—ideal for applications requiring temporary activation like emergency stops or machine starts. The actuator itself is designed with user-friendliness in mind: the mushroom shape provides easy actuation even when wearing gloves—a common requirement in industrial settings. It has a diameter of 40 mm which matches the cutout size required for installation ensuring compatibility with standard panel designs. Constructed with a metal bezel material ensures added durability against physical impacts while maintaining an aesthetic appeal often desired in modern equipment design. Finally, its red button color universally signifies stop functions or emergency operations enhancing visibility and safety on-site by offering clear operational cues at just a glance.
