OTTO HFNR

Forward, Neutral, Reverse Hall Effect Switch

The OTTO HFNR is compact, robust and reliable, ideal for grip or panel mount applications. This 3-position switch provides operator comfort by reducing the movement required to change direction or switch gears. Backlighting provides enhanced visibility; making them easy to see in poor lighting or nighttime operation. The electronics are sealed to IP68S; the switch has excellent EMI/RFI immunity, and a mechanical life of three million cycles.
