The Multiquip 0202005SB447 is a genuine OEM Centrifugal Switch designed for the ST-2005 submersible trash pump. As a factory-authorized replacement, this switch is built to the same specification as the original component, ensuring correct electrical response and motor protection. Sourced directly through Multiquip's OEM parts program, the part is the right part for operators who need a dependable, spec-matched repair on their ST-2005.
Key Features
- OEM-Spec Switching Thresholds — Engineered to the exact rotational speed trigger points required by the ST-2005 motor, so the starting winding disconnects at precisely the right moment.
- Direct Drop-In Replacement — Matches the original mounting configuration and electrical connections of the ST-2005, allowing a straightforward swap without improvisation.
- Confirmed ST-2005 Fitment — Verified for Multiquip ST-2005 submersible trash pump applications; use model code ST-2005 when confirming compatibility.
- Motor Protection at Every Start Cycle — A correctly functioning centrifugal switch prevents the starting winding from staying energized during run, protecting the motor from overheating and premature failure.
- Genuine Multiquip OEM Part — Supplied under Multiquip's OEM parts program, so you get the same component that left the factory — not an approximation.
A centrifugal switch is an electrically operated switch built into a single-phase AC motor that uses centrifugal force to control the starting winding circuit. During startup, the starting winding is energized to generate the torque needed to bring the motor up to speed. Once the motor reaches approximately 70–80% of its operating speed, the centrifugal mechanism actuates and opens the circuit to the starting winding, allowing the motor to run on the main winding alone. If the switch fails to open, the starting winding stays live and will overheat rapidly, causing motor burnout. If it fails to close on startup, the motor will struggle to turn over or won't start at all — both scenarios can put an ST-2005 pump out of service quickly.
