Features and benefits:

• Stay-put 3-position operation at +/-45° with no spring return, enabling mode selection that holds its position without operator input.
• Key-operated actuator (Key 455) with key removal allowed in any position, providing access restriction and machine interlocking capability.
• High ingress protection ratings (IP66, IP67, IP69, IP69K) suit demanding industrial environments with washdown or high-pressure cleaning requirements.
• Chrome-plated metal body with Zamak mounting frame offers robust mechanical durability rated to 1,000,000 operating cycles.
• Silver alloy (Ag/Ni) contacts deliver reliable electrical performance across AC-15 and DC-13 duty categories up to 600 V.

Applications:

• Industrial machine control panels requiring keyed mode selection or access restriction.
• Automation and process control systems where a stay-put selector switch prevents accidental position changes.
• Food and beverage or washdown environments requiring IP69K-rated operator devices.
• Marine and offshore control panels where DNV and Lloyd's Register certification is required.
