Robertshaw 5500-235 Infinite Switch

The Robertshaw 5500-235 Infinite Switch is a high-performance 240V infinite switch designed as a versatile replacement for cooking equipment heating elements. This 5500 M Series commercial-grade control provides precise proportionate control of resistive loads, making it essential for electric ranges, hot plates, and warming drawers. Featuring a 5% input at low, this switch ensures granular temperature management across the entire dial rotation. As a voltage sensing infinite switch, it replaces legacy VSI and INF series models, offering a smaller footprint to fit tight control panels without compromising electrical integrity.
