MDI Mercury Displacement 35NO-24A Contactor 326058-756 the DFM series functions asThe MDI Mercury Displacement 35NO 24A Contactor is a heavy duty single pole normally open 24V switching solution designed for high cycle industrial and HVACR environments. Built for reliability where standard electromechanical relays fail, this 35 amp mercury relay utilizes a liquid mercury contact interface to provide a fresh conduction surface for every cycle. This displacement technology significantly reduces contact pitting and oxidation, making
