KSI Series Infinite Switch

Application: Commercial Cooking

The Robertshaw^® KSI Series Infinite Switch is a current sensitive rotary switch. A current sensitive switch must be matched to the specific wattage of the heating element. A KSI switch controls the power dissipated by a heating element. It is used on electric ranges, hot plates, warming drawers and zones, barbecue grills, space heaters, quartz heaters and many applications which call for proportionate control of a resistive load.
