The Robertshaw® M series infinite switch is a rotary switch which 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.
5500 Infinite Uni-Kits include adaptors for screw or palnut type mounting. Kits include dial adaptors to allow the customer's dial to be used. Kits are available with white dials, black dials or no dial. All kits have a dial shaft with easy break-off grooves which can be taken off to match various shaft lengths.
