Duke 5580-2 Infinite Control Switch

This infinite control switch is used in commercial heating equipment to regulate heat output by controlling the electrical power supplied to the heating element. Operating on a 120V electrical system with a 13 AMP rating, the switch provides gradual heat adjustment instead of fixed temperature positions, helping support controlled warming operation. The switch features an EGO-style design with a flat-down mounting configuration and palnut mounting system, along with a four-screw hole arrangement for secure installation in compatible equipment. Its slotted shaft connects with a compatible control knob to allow manual adjustment of heat settings during operation. Commonly used in commercial warming equipment, this switch helps maintain adjustable heat control in food warmers, holding cabinets, and similar heating units. When the original switch becomes worn or unresponsive, replacing it helps restore normal heating adjustment and reliable equipment operation.

Basic heat control applications for Duke infinite switch systems include commercial food warmers, holding cabinets, and similar heating units where manual temperature adjustment is required. This Infinite Switch 5580-2 is compatible with commercial equipment from brands such as Duke, Thurmaduke, Aerohot, Economate Series, Heritage, and E-Series warming units, and other similar warming equipment where variable heat control is used for operation.
