L15204S Single Phase Generic Mechanical Centrifugal Switch — 20A motor starter, brake and clutch controller A straightforward, reliable mechanical centrifugal switch for singlephase motors and motor control applications. The L15204S uses centrifugal action to change contact state as a motor reaches operating speed, providing dependable startwinding switching and on/off control for brakes or clutches. It is a practical replacement or upgrade for singlephase induction and compatible servo motor systems that require a 20A rated mechanical switch. Key benefits Reliable automatic switching: mechanically opens or closes contacts based on motor speed to remove start circuits or engage control devices without electronic sensing. Simple, serviceable design: easy to install or in existing starter, brake or clutch control assemblies. Versatile control role: works as a starter switch, brake/clutch controller, or part of a motor protection/engagement circuit. 20A capacity: suitable for many singlephase motor starter and accessory control applications where a mechanical centrifugal switch rated to 20 amps is required. Core features and attributes Model: L15204S (exact model identification for ordering and replacement). Operation: singlephase mechanical centrifugal action — switches contact state as rotational speed changes. Rated current: 20A (appropriate for circuits and loads within this rating). Application focus: induction motors, compatible servo/electric motors, motor brakes and clutches, starter circuits. Form factor: compact mechanical assembly intended for integration in motor control housings or replacement of likeforlike centrifugal switches. Durability: designed for repeated mechanical operation typical in motor start/stop cycles. Compatible uses and applications Singlephase motor starters: automatically disconnect start windings once the motor reaches operating speed, enabling reliable starting and normal running without complex electronics. Motor brake or clutch control: engage or release mechanical brakes and clutches based on shaft speed to prevent abrupt engagement at speeds or to ensure safe stopping. Replacement part for maintenance: swap in the L15204S where an OEM or vintage centrifugal switch of similar function is required for or refurbishment. Installation and suitability notes Intended for singlephase motor systems and related control circuits that call for a mechanical centrifugal switch rated at 20A. Confirm mechanical fit and terminal compatibility with your motor or control assembly before installation. As a mechanical device, it is used where simple, fast, and robust switching based on shaft speed is preferred over electronic sensing. Suitable for workshop or field replacement by qualified personnel familiar with motor wiring and safety procedures. Ordering and identification Specify model L15204S when ordering to ensure correct match with singlephase centrifugal switch requirements and a 20A rated control function. Use the L15204S when you need a dependable, mechanical centrifugal switch for singlephase motor starting, brake or clutch control and straightforward replacement in motor starter assemblies.
