The SQUARE D 9007B19 is a replacement roller lever accessory designed for use with SQUARE D 9007-series limit switches. The lever measures 7.6 inches in overall length and features a steel roller, making it suited for industrial and commercial control applications where a durable actuating arm is needed to trigger a limit switch under mechanical contact. Electricians and controls technicians install this part as a direct replacement when an existing roller lever is worn, damaged, or missing. At 0.1 pounds, it is a lightweight component that integrates directly with compatible 9007-series switch bodies.
This roller lever is intended for use in industrial machinery, conveyor systems, automated equipment, and other electromechanical control installations where limit switches monitor position, travel, or end-of-stroke conditions. It is compatible with specific 9007-series SQUARE D limit switch bodies and is sold as a single unit. The steel roller construction suits environments where repeated mechanical actuation is expected over the service life of the switch assembly.
Designed for use with the following SQUARE D limit switch models: 9007AS9, 9007BS9, 9007CS9, 9007FT, 9007NS9, 9007T, 9007T10S9, and 9007T5S9.
Installation is typically performed by a licensed electrician or qualified controls technician. De-energize and lock out the control circuit before removing or installing any limit switch component, following NFPA 70E lockout/tagout procedures. Verify that the replacement lever length and roller material are appropriate for the actuation geometry and environmental conditions of the application before installation.
