The APEM Panel Switches 6648-03LM is a double pole industrial toggle switch designed for military-grade reliability. Featuring nickel-plated bushings, bright chrome plating, and a 10,000-cycle electrical life, this switch operates within -40°C to +85°C and meets stringent insulation and dielectric strength requirements for demanding environments. Ideal for critical control applications requiring robust performance.
The APEM Panel Switches 6648-03LM is a double pole industrial toggle switch engineered for military applications, delivering exceptional durability and precision in high-stress environments. With a maximum torque of 1.50 Nm for secure assembly, 1,000 MΩ insulation resistance at 500 VDC, and dielectric strength of 2,000 Vrms (50 Hz) between terminals and 3,000 Vrms (50 Hz) between terminals and frame, this switch ensures reliable operation across extreme temperature ranges from -40°C to +85°C. Its nickel-plated bushing, lever, and upper nut construction, combined with bright chrome-plated locking levers that provide three secure positions, makes it a robust solution for critical control systems where electrical integrity and mechanical resilience are paramount.
The APEM Panel Switches 6648-03LM delivers robust electrical performance with a minimum insulation resistance of 1,000 MΩ at 500 VDC and dielectric strength of 2,000 Vrms (50 Hz) between terminals and 3,000 Vrms (50 Hz) between terminals and frame. This ensures reliable operation in high-voltage environments while maintaining safety standards for critical applications.
Engineered for extreme conditions, the switch operates within a temperature range of -40°C to +85°C (-40°F to 185°F), making it suitable for military and industrial settings where temperature fluctuations are common. Its construction with diallylphthalate (DAP) case and sealing features ensures long-term reliability in harsh environments.
With a maximum torque of 1.50 Nm (1.10 Ft.lb) applied to the nut, the switch is designed for secure installation without compromising performance. The nickel-plated bushing, lever, and upper nut, combined with bright chrome-plated locking levers that provide three locked positions, enhance mechanical stability and ease of use.
The switch includes front panel sealing with one O-ring and sealing washer, ensuring protection against dust and moisture. Neoprene protection caps and sealing options are available, providing additional defense in demanding environments where contamination is a concern.
