Jet jt9-jbg8a-66 Centrifugal Start Switch

Product Description

The JET jt9-jbg8a-66 is a centrifugal start switch designed as a replacement component for electric motor-driven power tools and equipment. Centrifugal start switches disconnect the start winding from the motor circuit once the rotor reaches a set operating speed, protecting the winding from overheating during run conditions. This component is installed by electricians and qualified equipment technicians performing motor repairs or rebuilds on JET-branded machinery.

This start switch is a direct-fit replacement part intended for use in JET power tool applications. Centrifugal start switches of this type are commonly found in single-phase induction motors used in stationary shop equipment such as lathes, grinders, and similar motor-driven machinery. Install this part during motor servicing when the existing switch fails to open at speed or causes the motor to hum without reaching full RPM.

Key Features

• Centrifugal mechanism disconnects start winding at operating speed to prevent winding burnout
• OEM replacement part number jt9-jbg8a-66 for JET equipment
• Designed for single-phase induction motor applications in stationary power tools
• Direct-fit replacement to simplify motor rebuild and repair

Compatibility

Designed as an OEM replacement centrifugal start switch for JET power tools and accessories. Verify the part number jt9-jbg8a-66 against the motor nameplate or equipment parts diagram before ordering.

Installation Notes
