Parameters Category Parameter Specification for M2SSK2-201-10 General Product Type Modular, Illuminated Key-Operated Selector Switch (Operator) Series M2S (System M2S) Assembly Type Front Operator Module with Key & Integrated Indicator Mechanical Design Actuator Type Key-Operated Switch Key Positions 2-Positions (e.g., 0-1) as per "-201" code. Key Removal Typically removable in "0" (OFF) position. Actuator Size Likely 30mm diameter (based on "K2" common designation). Front Bezel Material Stainless Steel AISI 316 Key Material Nickel-plated Brass or Steel Electrical (Illumination) Integrated Indicator 10mm Diameter Indicator Light ("-10") Light Source LED (standard) Voltage for Light Requires separate M2S LED module (e.g., 24V DC, 110V AC). Switch Configuration Electrical Positions Defined by the contact block. The "-201" suggests a common configuration (e.g., 1 changeover contact breaking before making across two positions). Operational Mechanical Life > 100,000 cycles (key operations) Key Systems Unique key profile (variations available: different key codes, master keys). Environmental & Certifications Protection Degree (IP) IP66 / IP67 (when assembled with seal & approved enclosure) Hazardous Area Certification ATEX/IECEx: Ex d IIC T6 Gb / Ex e IIC T6 Gb (as part of complete certified M2S assembly). Corrosion Resistance Excellent (Stainless steel 316). Operating Temperature -25°C to +70°C (ambient) Compatibility & Assembly Required Components 1. M2S Contact Block (e.g., a 2-position block compatible with key actuator). 2. M2S LED Holder & LED Module (specific voltage). 3. M2S Sealing Ring. 4. M2S Certified Enclosure. Panel Cut-out 30mm or 22mm diameter (specific to "K2" variant; confirm with datasheet). Standards Compliance IEC/EN 60947-5-1, IEC 60529 (IP). Certifications CE, cULus, ATEX, IECEx.
