Safran Electrical & Power 8505K20 Safran Power 8505K20

The 8505K20 is a four-pole, environmentally sealed lever lock switch from the 8505 series, designed for military applications and compliant with MIL-DTL-3950. It features a locking actuator, thermoset molded housing, and an 15/32-32 UN-2A bushing thread with screw terminals. The switch supports both maintained and momentary action, with a mechanical life of 40,000 operations and an electrical life of 20,000 operations at rated load. Operating temperature ranges from -65°C to +71°C. The part is rated for 28VDC and 115VAC with current capacities of 4A resistive, 12A lamp, and 15A inductive for maintained contacts, and 2A resistive, 10A lamp, and 15A inductive for momentary contacts. The unit is equipped with standardized mounting dimensions and internal tooth lockwashers for terminal screws. Circuit configuration with lever in position corresponds to momentary contact with keyway-side locked-out center position.
