Eaton 5108A61G01 Auxiliary Switch Rotary Handle Mechanism

Eaton 5108A61G01 Auxiliary Switch Rotary Handle Mechanism is a rotary handle accessory designed for Eaton Cutler Hammer F, J, and K‑frame auxiliary switch assemblies. This part provides the manual rotary interface used to operate the associated auxiliary contacts within compatible frame-size equipment. Identified by the 5108A61G01 designation, it is intended for use with Eaton’s F/J/K‑frame family to ensure proper engagement with the corresponding switch hardware. When installed by qualified personnel, this mechanism translates a turning motion into actuation of the auxiliary switch, enabling control of circuits that require an auxiliary contact alongside the main switching function. This component helps ensure proper alignment and actuation when replacing worn rotary handles on compatible equipment, and it aligns with Eaton Cutler Hammer mounting patterns to support straightforward installation by technicians familiar with F/J/K-frame systems. In typical installations, the rotary handle mechanism works with the associated auxiliary switch to provide an additional point of control within Eaton's frame-compatible switchgear lineup.
