The Multiquip EM98119 Main Control Switch Assembly is a genuine OEM component designed for Mayco LS-series hydraulic concrete pumps, including the LS300, LS400, LS500, LS600, LS60TD, LS40D, LS40TD, LS50TD, LS600P, LS300P, and LS300G. As a factory-sourced replacement, the EM98119 meets the original design and electrical specifications required for safe, consistent pump operation. Sourced directly through Multiquip's authorized parts network, this assembly ensures a correct, direct swap with no guesswork on compatibility. If your Mayco LS-series pump is experiencing control issues or switch failure, this is the verified OEM replacement to restore full functionality.
Key Features
- OEM Electrical Specification: — Factory-matched switching capacity and circuit configuration ensures proper signal output to the pump's hydraulic control system.
- Direct Assembly Replacement: — Supplied as a complete switch assembly, making installation straightforward with original mounting points and connector interfaces.
- Broad LS-Series Fitment: — Confirmed for LS300, LS400, LS500, LS600, LS60TD, LS40D, LS40TD, LS50TD, LS600P, LS300P, and LS300G Mayco concrete pumps.
- Restored Pump Control: — A failed or damaged main control switch prevents the operator from commanding pump start, stop, and directional functions — replacing it restores full operational control of the machine.
- Electrical Safety Compliance: — As the primary operator interface for machine control, using the correct OEM-rated switch assembly is critical to safe and predictable pump operation on the jobsite.
The main control switch assembly serves as the primary operator interface on Mayco LS-series concrete pumps, routing electrical signals that command the pump's hydraulic system to start, stop, and regulate output. When this switch assembly degrades or fails, operators lose the ability to control pump functions reliably, which can disrupt concrete placement and create unsafe working conditions. Replacing it with the correct OEM assembly restores predictable, accurate machine response from the operator's position.
