The Multiquip KU31107101 Switch Assembly is a genuine OEM component designed for Whiteman walk-behind power trowel models BS90C, BH11C, BH90C, JS60C, JH90C, JH55C, and B46S90. Sourced directly from Multiquip, this switch assembly is built to the exact electrical specifications required by these machines. It installs as a direct replacement for the original unit, ensuring correct circuit operation without modification. If your trowel is experiencing ignition, shutoff, or control switching issues, verifying and replacing the KU31107101 is a logical first step.
Key Features
- Correct Electrical Specification — Genuine OEM construction ensures the switch meets the precise voltage, current, and contact rating required by Whiteman walk-behind trowel electrical systems.
- Direct-Fit Replacement — Engineered to match the original mounting configuration and connector interface on BS90C, BH11C, BH90C, JS60C, JH90C, JH55C, and B46S90 trowels.
- Broad Whiteman Trowel Coverage — A single part number covers multiple B-series and J-series Whiteman centrifugal-clutch walk-behind trowels, making it a practical stock item for mixed fleets.
- Maintains Reliable Operator Control — A correctly functioning switch assembly ensures the operator can start, stop, and control the trowel as intended — a worn or failed switch can result in erratic operation or a machine that won't start.
- Operational Safety Relevance — As a control switch on powered equipment, correct function is essential for safe machine operation and proper emergency shutoff response.
The switch assembly on a walk-behind power trowel serves as the primary electrical control interface between the operator and the machine's engine or motor circuit. It governs start and stop functions and, depending on configuration, may also manage safety interlocks that prevent unintended operation. When a switch assembly fails — through worn contacts, moisture ingress, or mechanical fatigue — the machine may become difficult to start, fail to shut down correctly, or behave unpredictably under load. Replacing a faulty switch assembly with a genuine OEM unit like the KU31107101 restores full, predictable electrical control to the trowel.
