Robertshaw 5502-136 Infinite Switch

The Robertshaw 5502-136 is a professional-grade infinite switch designed for precision heat control in commercial food service equipment. This 120V AC M-series rotary control offers a compact profile that fits into tight control panels where standard universal switches often fail to seat properly. Rated for resistive loads up to 15 Amps and wattage ranges from 100W to 3600W, it provides a linear power output with distinct low-to-high detents. The 5502-136M features a standard 2-1/8 inch "D" stem, making it a reliable OEM replacement part for a wide variety of electric ranges, griddles, and warming cabinets. Built for HVACR and commercial kitchen environments, this energy regulator manages ambient temperatures up to 180°F, ensuring stable performance under heavy-duty thermal cycling. When you need accurate kilowatt-hour regulation for resistive elements, this Robertshaw unit delivers the industrial-grade durability required by field technicians.

• Universal Compatibility: Compact M-series footprint facilitates easy retrofitting in equipment with limited mounting depth.
• Precise Variable Control: Voltage-sensing technology allows for smooth, incremental heat adjustment across the entire range.
• Industrial Durability: Rated for a maximum ambient temperature of 180°F to prevent premature failure in high-heat galley environments.
• Direct OEM Cross-Reference: Effectively replaces part number 5500-135 and other legacy INF series switches.

• What is the stem length and type? This unit features a 2-1/8 inch "D" style stem, compatible with most standard commercial control knobs.
• Will this work on a 240V circuit? No, the 5502-136 is specifically designed and calibrated for 120V AC operation. Using it on 240V will damage the internal bimetal heater.
• Is it a "Push-to-Turn" model? This is a standard non-push-to-turn rotary switch, providing immediate tactile response and detent positioning.
