Robertshaw 5500-113 Infinite Switch

The Robertshaw 5500-113 Infinite Switch is a high-performance 120V electric range control designed for precise temperature management of resistive heating elements. Engineered as a universal replacement infinite switch, this 5500 M Series model features a parallel circuit, voltage-sensing design that maintains linear control from low to high heat settings. With a 15 Amp resistive load rating, it provides stable power regulation for residential cooking equipment including ranges, hot plates, and warming drawers. Its small physical footprint allows for installation in tight control panels, while the 2-inch break-off shaft and included dial adaptors ensure compatibility with various OEM knob configurations.

When installing this Robertshaw 5500 series kit, technicians must mount the unit with the "TOP" orientation marking facing upward to ensure proper internal calibration. The switch replaces several legacy parts, including the Robertshaw INF-120-599B and various 3, 5, and 7-heat rotary switches. Its 120V AC operation is optimized for a 22.5% input at the low detent, providing consistent simmering performance. This rotary burner switch is UL certified and built for industrial-grade reliability in high-temperature environments up to 180°F ambient.

• Universal Compatibility: Includes multiple dial adaptors and a square break-off shaft to match original equipment knobs and panel depths.
• Precise Power Regulation: Features a 22.5% low-end input for superior simmering control compared to standard binary switches.
• Space-Efficient Design: The 5500 M Series has the smallest physical dimensions in its class, facilitating easier retrofitting in crowded appliance consoles.
• Broad Application: Suitable for a wide range of resistive loads, from standard electric cooktops to specialized food service warming equipment.

Is the Robertshaw 5500-113 a direct replacement for my existing switch?
Yes, it is designed to replace the common INF-120-599B and VSI series switches. Use the included terminal markings (L1, L2, H1, H2) to match your existing wiring configuration following the provided schematic.

Does this switch include a new dial?
No, this kit is designed to utilize your original equipment dial. It includes a "sprue tree" of adaptors to ensure the old knob fits the new 1/4-inch D-shaft or break-off shaft perfectly.

Can I use this 120V switch on a 240V element?
No. The 5500-113 is specifically rated for 120V AC applications. For 240V elements, you must select the appropriate 240V model to avoid component failure or hazardous electrical conditions.
