Heavy Duty Hesitation Switches
Antiplugging, Hesitation, Positive Stop or Positive Off Switch.
The most common application for the Heavy Duty Hesitation is to help prevent motor damage resulting from the high current generation by counter EMF of the armature at the time of reversing. This type of device is referred to as an anti-plugging, hesitation, positive stop or positive off switch.
One-Hole Panel Mount: These heavy duty toggle switches are available in either two- or three-position. The three-position switches offer a unique positive center stop feature, which assures that the lever cannot be thrown from one side through the center OFF position without stopping. This design feature is a major
factor in their widespread acceptance for motor reversing and speed control applications.
Flush Mount: These three-position switches also offer the positive center stop feature where the lever cannot be thrown from one side through the center OFF position without stopping. The high ratings of this series allow it to be used with a broad range of heavy duty applications. Copper contacts and brass screw terminals are standard.
