Eaton E34VMBK1 Knob Type Operator 30.5 Mm

Product Description

The EATON E34VMBK1 is a 30.5 mm knob type operator designed for use with modular pushbutton and selector switch assemblies in industrial control panels. This operator serves as the actuating component that interfaces with an operator's hand to mechanically engage or disengage the contact block beneath it. The 30.5 mm mounting diameter fits standard panel cutouts common across a wide range of industrial enclosures and control stations. Weighing just 0.25 pounds, it is a compact, lightweight component suited for panel builders and electricians working on machine control and process automation systems.

The E34VMBK1 is typically installed in control panels, operator stations, and industrial machinery where reliable manual input is required. Applications include motor control centers, conveyor systems, pump controls, and general-purpose machine operator interfaces. It is intended for use as part of a modular 30.5 mm control station assembly, paired with the appropriate contact blocks, legend plates, and mounting hardware to complete a functional switch assembly. Installation is handled by licensed electricians or qualified panel builders following applicable NEC guidelines.
