The 2644LH/2A212000L0 is a double-pole power rocker switch from the 2600 series designed for panel-mounted applications with screw terminals and clamp connections. This switch features an ON-ON-ON electrical function across all four positions (III A2-A1 B5-B4, II, I A2-A3 B5-B6, and IV), providing versatile switching capability for power control applications. The switch is rated for 10 A at 250 VAC (UL 61058) and 10 A at 24 VDC or 8 A at 12 VDC, with an initial contact resistance of 10 mO maximum and insulation resistance of 1,000 MO minimum at 500 VDC. It operates reliably over a temperature range of -20°C to +85°C with silver contacts, features a dielectric strength of 2,500 Vrms at 50 Hz between terminals, and is rated for 10,000 electrical cycles at full load. The switch is UL and CE approved, making it suitable for industrial control panels, power distribution systems, and equipment requiring robust, multi-position switching functionality.
