Singer Pneumatic Transducer – Foot Control Unit

988549-002

OEM Singer Air-Control Transducer for Smooth Variable Speed Operation

Singer Transducer 988549-002 is a genuine OEM pneumatic foot-control module engineered to deliver exceptionally smooth, responsive speed control for a wide range of Singer home sewing machines. Unlike traditional mechanical pedals that rely on a simple rheostat or spring-pressure switch, this air-driven transducer uses a pneumatic pressure system to translate foot movement into precise electronic speed signals. The result is a cleaner, more controlled acceleration curve and far superior fine-speed modulation — an advantage for quilters, garment makers, free-motion stitchers, and anyone who needs consistent, dependable stitch control.

#988549-002 restores the machine’s original responsiveness and keeps the motor operating within safe, intended tolerances. This foot-control unit is built to exact factory specifications, ensuring correct pressure sensitivity, connector alignment, airflow calibration, and electrical compatibility with Singer’s mid-range and advanced domestic models.

Whether you are repairing a failing pedal, upgrading from a worn controller, or refurbishing a machine for long-term use, the Singer 988549-002 transducer offers the reliability, accuracy, and performance that only a true Singer-engineered component can provide.
