The TORQ Syncrosnap® centrifugal switch controls the start winding in single-phase electric motors. A centrifugal switch consists of two parts;

  1. A centrifugal mechanism which rotates on the motor shaft and interacts with
  2. A fixed stationary switch with electrical contacts which control the start-winding circuit.

TORQ Centrifugals are more accurate and have a longer life which helps reduce warranty costs for OEMs. The crisp snap action of the spring helps eliminate creeping, chattering, and reduces arcing. TORQ Centrifugal switches are recognized around the world for superior durability and performance. TORQ specializes in two-speed motor applications.
