Robertshaw 5500-102 Infinite Switch

The Robertshaw 5500-102 Infinite Switch is a high-performance 120V infinite control designed to regulate power for resistive heating elements in electric ranges, hot plates, and commercial warming equipment. This parallel circuit voltage sensing switch is a direct replacement for the Robertshaw 5500-102M and INF-120 series, delivering a precise 5% low-input calibration. Engineered for durability, it features 1/4-inch male quick-connect terminals (L1, L2, H1, H2, and P) and is rated for 15 Amps at standard operating temperatures. The unit includes a 2-inch break-off shaft with a universal "A" stem profile and comes with multiple shaft adapters to accommodate original equipment dials. Its double line break capability ensures safe disconnection, while the non-push-to-turn mechanism provides reliable tactile feedback during operation. This Uni-Kit is optimized for technical reliability and ease of installation in narrow control panels.

• Universal Compatibility: Includes specialized shaft adapters and a 2-inch break-off stem to fit most OEM configurations without requiring a new dial.
• Precision Calibration: Maintains a steady 5% input at Low, ensuring consistent simmer temperatures for professional-grade heating applications.
• Compact Footprint: The low-profile M-series housing allows for seamless integration into tight control boxes where standard switches may fail to fit.
• Industrial-Grade Construction: UL recognized and rated for resistive loads up to 15 Amps, providing superior heat dissipation and long-term terminal integrity.

Is the 5500-102 compatible with my current 5500-102M switch?
Yes, the Robertshaw 5500-102 and 5500-102M are technically identical in performance and terminal configuration. The 'M' designation typically refers to modern manufacturing updates to the low-profile housing.

Can I use this switch on a 240V circuit?
No, this specific model is a 120V AC infinite switch. Utilizing a 120V rated control on a 240V circuit will cause immediate component failure. Ensure your power supply matches the 120V rating before installation.

How do I adjust the shaft length for my appliance?
The universal break-off shaft features pre-scored grooves. Use two pairs of pliers to grip the shaft on either side of the desired groove and apply steady pressure to snap it to length. Never use the switch body for leverage during this process.
