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 specializes in two-speed motor applications.

Torq Centrifugal are more accurate and have a longer life which reduce warranty costs for OEMs. When a centrifugal switch fails, the motor can burn up the start winding and cause serious damage to the motor. Torq centrifugal switches offer better speed selection for durability and superior performance.
