emergency stop button partB
Product overview
The LYAN emergency stop switch features a highly visible design with red and yellow colors that comply with international safety standards, ensuring quick recognition and easy operation. The housing is made of anodized aluminum alloy (customizable in stainless steel), while the base uses flame-retardant material, offering excellent impact resistance, corrosion resistance, and flame-retardant performance. It is suitable for use in workshops, industrial machinery, construction sites, and other demanding environments.
The button surface is treated with an anti-slip texture, allowing for easy operation even while wearing gloves. The product supports multiple mounting hole sizes, such as 22mm and 25mm, and uses a nut-locking installation method for quick and secure mounting. It offers flexible contact configurations, including 1NO/1NC and 2NO2NC, compatible with a wide range of control systems. Optional features include illuminated versions, key reset types, and twist-to-reset structures to meet diverse application needs.
The distinctive metallic appearance enhances both safety and product recognition while improving overall stability. LYAN also provides rear waterproof sealing solutions and custom cable options, allowing the emergency stop switch to function reliably in wet or humid environments and greatly simplifying installation.
