Mercury Relays and Contactors


Typical applications include:


   Electric Heaters on plastic extruders, drying ovens, injection moulding machines and glass furnaces.


   Lighting for street lamps, airport runways, stage lighting and flood lights.


   Motor starting, air conditioning, battery chargers, test panels and mining equipment.


Available from ICD Controls is the Mercury Displacement Industries' (MDI) range of mercury relays and contactors for high power switching applications.  They extend in size from 30 Amp to 100 Amp in single, two, three or four pole configurations and offer a low cost and very reliable alternative to conventional relays and contactors.  Standard coil voltages range from 6 VDC to 250 VDC and 24 VAC to 480 VAC, which cover the majority of applications.  Non-standard coil voltages are available on request.


When compared to other high power switching products, MDI mercury relays and contactors are a very low cost alternative, resulting in substantial savings.  Furthermore, with such a long useable life, they continue to save money well after inferior products would have failed.


Using their experience with mercury switching products, MDI has developed a range of Tilt Switches, Proximity Switches and Liquid Level Control Floats.  These are again manufactured to MDI's high standards and are available in numerous forms to suit many applications.
