Stationary Switches

The stationary switch is the current carrying component of the TORQ Syncrosnap® centrifugal switch. These switches are designed to fit within the motor with a minimum of assembly time required. They can also be furnished to perform secondary functions when the equipment attains full speed.

Each unit size can be utilized for single-contact, dual-contact, multi-speed and added features of multiple circuitry when needed. Terminal board arrangements are also available for field connection changes in speed, direction, etc. when desired.
