The 100DP1K2B25M1QEH is a DPDT (double-pole double-throw) rotary switch featuring a three-position locking mechanism with positions for ON, NONE, and ON states. The switch is rated for 2A at 250VAC or 5A at 120VAC/28VDC, with silver contact material and an electric life of 6,000 make-and-break cycles at full load. It operates reliably across a temperature range of -40°C to 85°C and provides 1,000 megaohm minimum insulation resistance with 1,000 V RMS dielectric strength. The switch includes a 1/4-40 UNS-2A threaded shaft for secure panel mounting with a standard locking ring, keyway, and epoxy-sealed knob assembly. This design makes it ideal for industrial control panels, machinery interfaces, and applications requiring reliable multi-position switching with mechanical locking.
