The APEM Panel Switches 3549-001NA12 is a double pole lever switch with three positions (ON-OFF-ON) designed for industrial applications. Featuring bright nickel finish, locked in 3 positions, and 175 mm standard lever length, it offers high durability with 40,000 cycle mechanical life, 10 mΩ max contact resistance at 1 A 2 VDC, and complete sealing against 0.1 bar pressure. Approved to CECC 96000 standards for reliable operation in temperatures from -40°C to +85°C.
The APEM Panel Switches 3549-001NA12 is a robust double pole lever switch engineered for demanding industrial environments. This switch provides a reliable ON-OFF-ON electrical function with a bright nickel finish and lever locking in three positions. Its 175 mm standard lever length ensures precise control, while the switch's complete sealing withstands 0.1 bar pressure for protection against environmental factors. With a mechanical life of 40,000 cycles and high dielectric strength (2,500 Vrms 50 Hz between terminals and 3,000 Vrms 50 Hz between terminals and frame), it delivers exceptional performance in harsh conditions. The switch operates within a wide temperature range of -40°C to +85°C and meets European CECC 96000 standards for safety and reliability.
The APEM Panel Switches 3549-001NA12 operates with a maximum contact resistance of 10 mΩ at 1 A 2 VDC. It features a dielectric strength of 2,500 Vrms 50 Hz between terminals and 3,000 Vrms 50 Hz between terminals and frame, ensuring robust electrical isolation. The switch supports a wide operating temperature range from -40°C to +85°C, making it suitable for extreme environmental conditions.
This switch is completely sealed to withstand 0.1 bar pressure, providing protection against moisture and contaminants. Its moisture resistance allows it to function reliably for up to 56 days in humid conditions without degradation. The switch is approved to European CECC 96000 standards, ensuring compliance with industrial safety regulations.
Engineered for high reliability, the switch offers a mechanical life of 40,000 cycles, ensuring long-term performance in demanding applications. The lever locking mechanism provides secure positioning in three distinct positions (ON-OFF-ON), while the 2 Nm (1.47 ft-lb) torque specification ensures tight and secure mounting without damage.
The switch features three terminal types and includes two hex nuts and one sealing washer for sealed mounting. Its double pole configuration allows for simultaneous control of two circuits, while the bright nickel finish enhances both aesthetics and corrosion resistance in industrial settings.
