Eaton Cutler-Hammer E34VFB120ER-1X Selector Switch

The Eaton Cutler-Hammer E34VFB120ER-1X Selector Switch is a red-illuminated electrical control switch designed to provide a clear, two-state selection using a single actuator. It is specified as a 2-position device featuring one normally open (NO) and one normally closed (NC) contact, collectively described as 1NO-1NC. The red illumination provides a visual cue for operators, helping to locate the switch and distinguish its active status in low-light environments. The model designation E34VFB120ER-1X identifies the exact configuration within Eaton’s Cutler-Hammer line, enabling precise pairing with other components that share the same family and footprint. With its two-contact arrangement and illuminated status indicator, this selector switch supports straightforward control logic in equipment where a simple, visible two-state input is required. Because it carries Eaton’s Cutler-Hammer branding, it aligns with other compatible parts for a cohesive electrical installation. Red illumination, two-position operation, and 1NO-1NC contact configuration are the key specifications highlighted by the model number.
