Key Features
- Genuine OEM Electrical Specification — Manufactured to exact resistance and circuit continuity specs, ensuring the switch actuates and interrupts the ignition circuit the same way the original did from the factory.
- Direct Connector Match — Plug-and-play replacement that connects directly to the existing wiring harness on supported models without splicing or adapter wiring.
- Broad Multiquip Fitment — Compatible with MC12PH, QPT405SLT, JH55C, JH90C, JS60C, BH90C, BH11C, and BS90C — covering concrete mixer, centrifugal pump, and walk-behind trowel applications in one part number.
- Restores Reliable Engine Shutdown — A worn or failed stop switch can prevent the engine from cutting out on command, leaving operators unable to shut down the machine quickly when needed.
- Critical Safety Component — The engine stop switch is a primary operator safety control; using a genuine OEM replacement ensures the shutdown circuit performs as intended under all operating conditions.
The engine stop switch assembly gives the operator direct electrical control over engine shutdown. When activated, it interrupts the ignition circuit, cutting power to the engine and bringing the machine to a controlled stop. This function is essential across all equipment types — from concrete mixers and pumps to walk-behind trowels — because it serves as the primary means of halting machine operation in both normal and emergency situations. A faulty or worn stop switch may fail to break the circuit reliably, causing delayed shutdowns or an engine that cannot be stopped by the operator, which poses a significant safety risk and can lead to accelerated mechanical wear.
