The APEM Panel Switches 6421A-03K-2V is a single pole autoswitch designed for reliable ON/OFF control in industrial and military applications. With an initial contact resistance of 10 mΩ max, insulation resistance of 1,000 MΩ min. at 500 VDC, and electrical life of 10,000 cycles at full load, this switch ensures robust performance across temperatures from -40 °C to +85 °C. Its front panel sealing with one O-ring and sealing washer provides protection for demanding environments.
The APEM Panel Switches 6421A-03K-2V is a single pole autoswitch engineered for precise ON/OFF control in industrial and military settings. This switch delivers exceptional reliability through its low initial contact resistance (10 mΩ max), high insulation resistance (1,000 MΩ min. at 500 VDC), and robust dielectric strength (2,000 Vrms 50 Hz min. between terminals and 3,000 Vrms 50 Hz min. between terminals and frame). Designed to withstand extreme temperatures (-40 °C to +85 °C), it ensures consistent operation in harsh conditions while maintaining electrical integrity over 10,000 cycles at full load. The front panel sealing with one O-ring and sealing washer provides effective environmental protection without compromising ease of use.
The 6421A-03K-2V switch ensures high electrical reliability 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. Its initial contact resistance remains below 10 mΩ, supporting stable electrical connections even under high current loads.
Engineered for extreme conditions, this switch operates reliably across a temperature range of -40 °C to +85 °C. The front panel sealing with one O-ring and sealing washer provides effective protection against dust and moisture, making it suitable for military and industrial environments where environmental exposure is a concern.
With a maximum torque of 1.50 Nm (1.10 Ft.lb) for nut tightening, the switch ensures secure installation without damage. The black finish on the actuator and bushing offers both aesthetic appeal and resistance to wear in high-traffic areas.
Ideal for lighting and machinery applications requiring simple, reliable ON/OFF switching. The single pole configuration provides straightforward integration into control panels while maintaining high performance standards for critical operations.
