As a direct OEM replacement sourced through Multiquip's authorized parts network, the EM40711 meets the exact electrical specifications of the original component.

Key Features

• Genuine OEM Electrical Specification — Meets the original switching resistance and load rating required by the C30HD series pump control circuit, not a generic substitute.
• Direct Drop-In Replacement — Connects to the existing wiring harness using the original mounting position, so installation is straightforward on C30HD and C30HDNI models.
• Broad C30HD Series Fitment — Compatible with C30HD, C30HDNI, C30HDNI Precision, C30HDN, C30HDNI Zenith, C30HDG, C30HDZ, and C30HDGA concrete pumps.
• Restores Accurate Pump Control — A faulty 3 way switch can cause incorrect pump direction selection or loss of function; replacing it with EM40711 brings the control panel back to proper operation.
• Electrical Safety Compliance — Using the correct OEM-rated switch ensures the control circuit operates within its designed parameters, reducing the risk of wiring faults or unintended pump activation.

The 3 Way Switch on a Mayco C30HD series concrete pump is a control-panel component that allows the operator to select between multiple pump operating modes or directional states. When this switch fails or becomes worn, the operator may lose the ability to correctly direct pump function, leading to operational errors or a complete loss of control response. Replacing a damaged switch promptly with the correct OEM part keeps the pump responding accurately to operator input and prevents potential misfeeds or uncontrolled pump behavior on the job.
