L11D1EHN1-A7900-000 is an L-Series sealed rocker switch engineered for demanding industrial environments. The switch features IP67 certification for sealed front panel components and operates reliably across a temperature range of -40°C to +85°C. It accommodates a standard mounting hole of 1.734 x 0.867 inches (44.04 mm x 22.02 mm) with acceptable panel thickness ranging from 0.030 to 0.156 inches (0.76 mm to 3.96 mm). The switch offers extensive circuit flexibility with single or double pole configurations, multiple actuator styles, and up to twelve terminals for diverse switch and lamp circuit options, including LED or incandescent illumination. Its moisture resistance is validated per MIL-STD 202F Method 106F testing. This versatile design makes it ideal for construction machinery, agricultural equipment, and on-highway transportation applications where durability and environmental sealing are critical.
